5 Variation Table The ESD3 variants are distinguished firstly by their reset function and secondly by the configuration of the status relay contact. This can be implemented off-load both as open and closed. It is not a safety contact, but is exclusively used for transmitting information. It is not monitored for failure and must never be used for safety shutdown in any form whatsoever. Each type is available in three voltage supply variants: 4 V AC/DC, 5 V AC, 30 V AC.

9 Switching Units ESR5/6 Pin Plugable Socket GS-BE-7 and ZH /494 -/-Channel General The difference between the ESR5 and ESR6 is that the ESR6 has two separate evaluation circuits. Function Connected sensors are monitored with a terminating resistance of 8. kohm to detect changes in the constant flowing zero-signal current. Both relays are energised in the non-active condition. If one or more sensors are activated the total resistance drops towards zero ohm when the resistance falls below the defined limit (approx. kohm) the relays de-energise the yellow LED illuminates Connection max. total length of sensor with cable 50 m max. total area of sensor 5 m multiple sensors are connected in series the total resistance must not exceed 8. kohm Important: The installed fuse is absolutely neccesary. It protects the relay contacts against «welding» when overloaded. Suppressors (0 Ohms/0. μf) are to be connected across the connected loads. Periodical function test are to be made. The designated test contacts are to be bridged (see Layout). The applied tests are to be documented. Further installation instructions can be obtained from the operators manual enclosed with the product. When a fault occurs in the sensor circuit (cable breakage, sensor defect ) the total resistance increases when the resistance exceeds the defined limit (approx. 9 kohm) the relays de-energise the red LED illuminates Terminal/Connections Terminal ESR5 ESR6 A,A (,0) Supply 4VACDC Supply 4VACDC,3 (5,8) -Input -Input 4,34 (7,9) -Input (or 8. kohm) -Input, (,6) Safety-Output Safety-Output,4 (3,4) Safety-Output 3 () Bircher Reglomat AG, Wiesengasse 0, CH-8 Beringen, Switzerland, Phone +4 (0)5 687, Fax +4 (0)
