PowerLossMonitor PLM Liability disclaimer The manufacturer and the distributor of the measuring devices do not claim liability for damages or injuries of any kind resulting from an improper use or handling of the devices or the associated software. Neither the manufacturer nor the distributor can be held liable by the buyer or the user for damages to people, material or financial losses due to a direct or indirect use of the measuring devices.
PowerLossMonitor PLM Symbol explanations The following symbols and signal words indicate possible residual risks: DANGER Means that death or serious physical injuries will occur if necessary safety precautions are not taken. WARNING Means that death or serious physical injuries may occur if necessary safety precautions are not taken.
PowerLossMonitor PLM Introduction System description The PowerLossMonitor PLM is a system that determines power losses especially in water-cooled compo- nents of beam guidance systems. PLM 2/10/20 Display Red LED „Error“ Water flow rate is too low PLM 40 Red LED „Error“ Display Water flow rate is too low Fig.
Depending on the purpose of use and power, the devices are available with different configurations and con- nections: Designation Connections Power in kW Water In Water Out from Chiller to Absorber PRIMES bus PRIMES bus PLM 2 Safety Interlock T-Sensor external Analog Out Water In Water Out from Chiller...
X Do not use compressed air for emptying the cooling circuit. Installing the software For the operation of a PowerLossMonitor PLM with a PC, the PRIMES PowerMonitorSoftware has to be installed. Start the installation by double-clicking the file “PMS v.2.xx Setup” and follow the instructions on your screen.
PowerLossMonitor PLM Connecting the cooling circuit DANGER Fire hazard; Damage/Destruction of the device due to overheating If there is no water cooling or a water flow rate which is insufficient, there is a danger of overheating, which can damage the device or set it on fire. X Do not operate the device without a connected water cooling.
PowerLossMonitor PLM Humidity • The device must not be operated in a condensing atmosphere. The humidity has to be considered in order to prevent condensates within and outside the device. • The temperature of the cooling water must not be lower than the dew point (see Tab. 7.1 on page 14). NOTICE Damage/Destruction of the device due to condensing water Condensation water inside of the device can lead to damage.

PowerLossMonitor PLM Connect the safety interlock The safety interlock protects the measuring device from damages by turning off the laser in case of an error. The device can be damaged in case of a low water flow rate. Whenever the water flow rate is too low, pins 1 and 4 are connected. In case the water flow rate is according to the operating conditions, pins 1 and 3 are connected.
+24 V Not assigned Tab. 8.2: Pin assignment PRIMES bus Connect the external temperature sensor The temperature sensor is a Pt100 with a four-wire connection. Plug the connector cable into the corre- sponding socket of the PowerLossMonitor PLM. The connection cable may have a length of up to 10 m.
NOTICE Damaging/Destruction of the device The supply voltage of 24 V is ensured by means of the RS485-based PRIMES bus. If the measuring device is directly connected with a PC, the computer may be damaged! X Only connect your PC with the measuring system via a PRIMES RS485/RS232 interface converter.
Connect the PC via the USB interface You can also connect the PC via the USB interface of the PowerLossMonitor PLM. In this case, the PRIMES- RS485/RS232 converter is not needed and the power supply is connected directly via an adapter to the PowerLossMonitor PLM (see Fig.
PowerLossMonitor PLM 8.10 Analog output The analog signal is effected via the 4-pin device socket M8 (see Fig. 8.2 on page 17 or Fig. 8.4 on page 18 and Fig. 8.5 on page 19). The output voltage is 0 V ...10 V. A suitable connection cable is included in the scope of delivery.
Display the measuring values in the display or the PowerMonitorSoftware PMS The measured values are displayed on the integrated display or can also be displayed on a PC via the PRIMES bus or the USB-interface. This requires the PRIMES PowerMonitorSoftware PMS (included in the scope of delivery).
