Insulation monitor RN 5897/300
Safety for mobile generators The insulation monitor RN 5897/300 from the VARIMETER IMD series by DOLD was developed especially for use with mobile generators. In mobile applications, such as in emergency vehicles or on construction sites, electrical energy must be used to reliably prevent injuries and property damage. Furthermore, mobile generators need to guarantee immediate operational readiness, without requiring time-consuming procedures to set up safeguards (such as installing and calibrating grounding systems etc.). That’s why the safeguard “electrical separation with insulation monitoring and shutdown” is available. It triggers an automated shutdown within < 1 s if the insulation resistance sinks below 100 Ω / V. The RN 5897/300 meets these demands, and fulfills the requirements of DIN VDE 0100-551 for mobile generators. The insulation monitor is suitable for system leakage capacitance of up to 30 μF, and is designed for universal use in ungrounded AC, DC and AC/DC networks. Besides an adjustable alarm threshold, the insulation monitor also has an adjustable pre-alarm threshold. A multicolored LED status light keeps users informed continuously on the current operating status. The device enables reliable monitoring, even in a network without current.
Insulation monitor RN 5897/020
Insulation monitoring for DC charging stations The number of electric vehicles is constantly increasing and will grow even faster in the future. This will also drive forward the expansion of the charging station infrastructure, as DC charging stations are the first choice when electric vehicles need to be charged in the shortest possible time. Electrical safety must be guaranteed during the charging process. For this purpose, an unearthed DC power supply system (IT-grid) with insulation monitoring is set up and monitored by means of an insulation monitoring device (IMD). The user must never be exposed to high voltages (up to 1000 V) at any time. The insulation monitor RN 5897/020 of the VARIMETER IMD family is used especially for DC charging stations according to the IEC/EN 61851-23:2014/AC:2016-06 standard and monitors the charging process from the charging station into the vehicle. The device is characterised by the short response delay of ≤ 1s, a rated voltage up to DC 1000 V with coupling device and the detection of asymmetrical as well as symmetrical insulation faults. The integrated voltage measurement ensures reliable detection of the insulation resistance in the IT grid. The insulation monitor also features a selftest. This takes place automatically after power-on and after every full operating hour.
Insulation monitor RN 5897/010
Insulation monitoring for modern IT systems The demand for the availability of machines and apparatus in the region of factory machinery and process technology is constantly increasing. The requirement for this is a functioning and reliable power supply. Unexpected insulation faults in the system can lead to unwanted power supply failures, and even cause personal injury or property damage. This is why insulation monitoring equipment is typically used in IT systems. The insulation monitor RN 5897/010 from the VARIMETER IMD series by DOLD was developed especially for use with modern power supplies. These are often comprised of converters, thyristor regulators, and direct current components. Through EMV interference suppression measures, high leakage capacitance onto the ground is present. The RN 5897/010 is suited for system leakage capacitances of up to 1000 μF, and for voltages up to AC/DC 230 V. Using the additional ballast unit RR 5898, it is possible to install the unit in systems with voltages of up to AC 1000 V and DC 1500 V. Besides an adjustable alarm threshold, the insulation monitor also has an adjustable pre-alarm threshold. A multicoloured LCD screen constantly updates stating the current insulation value. The insulation monitors guarantee additional surveillance over current-free networks. A selective earth fault detection of L+ and L- enables quick fault localisation.
Energy meter RL 9405
Energy management means the continuous monitoring, storage and evaluation of energy measurement data, thereby increasing the transparency of energy consumption and energy costs at all measurement levels. Only with a detailed overview of the energy consumers, the use of energy can be designed in a demandoriented and efficient manner and thus, for example, offering optimisation potentials. The energy meter RL 9405 of the VARIMETER PRO series is used to measure electrical parameters and energy consumption in 3-phase mains with neutral conductor. Voltages and currents are measured and evaluated continuously. A separate auxiliary voltage is not required. The device provides up to 50 characteristic values of the energy supply and that with a compact width of only 35 mm. The RL 9405 determines all energy consumptions and enables a breakdown by cause. The energy meter RL 9405 is predestined for use in manufacturing processes and IT data centres, to detect energy saving potentials and is especially suitable for the fulfilment of energy audits (DIN EN 16247-1) or energy management (ISO 50001). The galvanically separated Modbus RTU interface offers flexible options for processing information directly via a gateway or a higher-level control system (PLC) and passing it on via standardised interfaces.
Insulation fault location system RR 5886 / RR5887
Precise localisation of faults during operation The fault-detection process for insulation faults can become a costly and time-consuming process in extensive industry systems. The insulation fault location system of the VARIMETER EDS family from DOLD, consisting of a test current generator RR 5886 and the insulation fault search device RR 5887, monitors and locates insulation faults in a quick and safe manner in complex, isolated AC/DC mains (IT systems). The Modbus RTU interface allows a fast connection of the devices into existing bus systems. The corresponding current transformers ND 5017 work independent of each other. They are simply connected to the input channels of the fault locating module RR 5887, which also calibrates them. Insulation fault search devices can notably be used advantageously in complex and widespread power supply systems. Even computer centres, which are operated in unearthed mains (IT system) due to availability and insensitivity to disruption, benefit from the use of an insulation fault location system. Faulty electrical circuits can be found and removed quickly before a system break down with loss of data. The information about the location of the fault are visualised directly on the RR 5887 insulation fault search device. In addition the actual fault current values can be read, localised and visualised via Modbus. The insulation fault location system allows for automatic and quick pinpointing of faulty electrical circuits, thereby increasing reliability and system availability. You will very quickly recoup the purchasing costs for the insulation fault location system thanks to reduced maintenance costs and eliminated service interruptions. Some application examples include power plants, shipbuilding, traffic engineering, industrial systems, PV systems etc.

With its large measuring range of DC 20 - 1000 V, the voltage relay UG 9431 can be used in a wide variety of industrial applications. - 2 parameterisable relay outputs - Simple parameterisation, monitoring and diagnostics via Modbus RTU - Optimised system operation thanks to preventive maintenance
Multifunction measuring relay UG 9400 - with Modbus RTU
Trouble-free and economic operation of machinery and plant is greatly improved by the reliable and continuous monitoring of single and 3-phase mains. Especially for pumping stations, fan drives and signalling systems where preventive maintenance measures or early fault detection is indispensable. If different parameters have to be monitored simultaneously, the investment, maintenance, operating and installation costs will be increased. With the multifunction measuring relay UG 9400 from the VARIMETER PRO series, DOLD combines up to 9 monitoring functions in one device with a width of only 22.5 mm and also enables parameterisation and monitoring via Modbus. Depending on the requirements, the UG 9400 can simultaneously monitors the 3-phase mains for overvoltage/undervoltage, voltage unbalance, overcurrent/undercurrent, cos ij, active, apparent and reactive power, frequency and phase sequence. It can also be used in single-phase mains applications. The compact UG 9400 measuring relay, also has two output relays which can be configured independently for different parameters. Commissioning, parameter setting and monitoring is quick and easy via a Modbus RTU interface. This fieldbus connection saves wiring and offers extensive diagnostic options, which increase the reliability and availability of machinery and plant. In many applications, the simple integration of Modbus RTU enables cost effective central monitoring of measured electrical variables, especially in applications with complex and extensive plant.
Three-position enabling switch RE 6909 - Safe and ergonomic
When operating machines and devices there are operating modes and situations where the stay in hazardous areas is needed. In order to work safely even in these cases with increased danger additional measures are required. With the new three-stage enabling switch RE 6909 of the SAFEMASTER series, people are secured during commissioning, maintenance or setup. What is important here is the three-stage functionality. Only an actively operated middle position gives approval to a higher-level safe control. If the operator releases the three-stage enabling switch or pushes it through (panic function) he or she withdraws approval, thus releasing the safety-oriented switch-off. Thanks to its functional and ergonomic design, the enabling switch grants fatigue-free working and, due to its modular setup, many additional operating and control functions such as a start-stop control device, key switches and further buttons. The robust handheld terminal meets the IP65 requirements for use even in rough ambient conditions. With the new three-stage enabling switch RE 6909 of the SAFEMASTER series we are expanding our product range of wireless enabling switches and wireless emergency stop systems for the safety-oriented transmission of emergency stop and control functions by an ergonomic wired version.

Standstill monitor UG 6946
Safe sensorless standstill monitoring The safe sensorless standstill monitor UG 6946 from the SAFEMASTER S series detects the standstill of 3-phase and 1-phase motors independent of the direction of rotation. This means sensors such as encoders or proximity switches are not required. Access to the danger zone of a system is only possible by the enabling signal of the standstill monitor after the drive has been switched off and run down. In order to detect a standstill, the remanence voltage induced by the motor windings is evaluated and provides safe standstill monitoring up to Cat. 4 / PL e or SIL 3, even if the motor has already been switched off. Using a conventional release via a time control, dangerous movement could not necessarily be excluded. For the implementation of different operating modes, the standstill monitor UG 6946 also offers the possibility of bridging the standstill monitoring (muting). The simple integration into the machine and drive concept reduces the commissioning effort and costs and is particularly suitable for use in machine tools and woodworking machines, centrifuges and rolling drives. With a width of only 22.5 mm, the UG 6946 can be accommodated in the control panel even under tight space conditions allowing easy retrofitting. The device also offers two redundant safety contact paths and a forcibly guided signal contact.
Speed and standstill monitor UH 5947
More than just drive monitoring Regardless of whether the set-up operation must be monitored safely, protection via speed limitation is needed or a safety gate is released after detection of standstill - the speed and standstill monitor UH 5947 of the SAFEMASTER S series is the right choice for your application. The device can be operated via the 4 buttons on the front and the LCD display, thus enabling simple parameterisation. For example, the encoder type, speed limits per operating mode and delay times can be flexibly adapted to your application. During operation, the current speed values can be read directly at any time, which in particular makes commissioning easier. To prevent manipulation, the configuration can be protected against unintentional changes by means of a parameter lock after commissioning. For multiple use, the configuration can easily be transferred from unit to unit via interface. The device status or the current speed can further be processed by a control system via a semiconductor signal output. The speed and standstill monitor UH 5947 covers the combined application of encoder signals and PNP or NPN sensors. Alternatively, NAMUR sensor technology can be used as a device variant. The device can be used in temperature ranges from -20 to +60 degrees Celsius and up to heights of 4000 metres.
