Page 15: Wiring Diagram For Temperature Sensor
Electrical connection - continued - Attention Please observe the installation & operating manuals for the temperature transmitter TRV 5-40 and the temperature switches TRS 5-50 and TRS 5-52. Make sure that connecting cables leading to the equipment are segregated and run separately from power cables. -
Page 16: Troubleshooting
Troubleshooting Indication, diagnosis and remedy Attention Before carrying out the fault diagnosis please check: Supply voltage: Is the temperature transmitter or temperature switch supplied with the mains voltage specified on the name plate? Wiring: Is the wiring in accordance with the wiring diagram? Faults indicated by the seven-segment display (TRS 5-52) or the seven-segment display on the right (TRV 5-40, TRS 5-50) Error code... -
Page 17: Safety Note
Troubleshooting - continued - Safety note Safety temperature limiters/monitors are items of equipment with safety function (PED) and must only be installed, wired and commissioned by qualified and competent staff. Retrofitting and maintenance work must only be performed by qualified staff who - through adequate training - have achieved a recognised level of competence. -
Page 18: Removing And Disposing Of The Temperature Sensor
Removing and disposing of the temperature sensor Danger The temperature sensors TRG 5-63 or TRG 5-64 are screwed into vessels or pipes. When loosening the temperature sensor steam or hot water might escape! This presents the risk of severe scalding all over the body! It is therefore essential not to dismantle the temperature sensor unless the boiler pressure is verified to be 0 bar. - Page 19 For your Notes...
