English 18 ISK 74-312 Inductive Safety Relay Relay 8. Connecting the sensors 8.1 Connecting to the coil core SPK 54 (figure 1) The travelling edges (SCE) are connected to the travelling coil core. For this purpose, the travelling SCE CLOSING movement is connected to connection C of the travelling coil core and the optional SCE OPENING movement is connected to connection O . 9.2 Connecting multiple sensors per sensor circuit (figure 2) ASO sensors must not be connected in parallel. C O SCE OPENING movement SCE CLOSING movement Figure 1: Connection at the coil core If a channel is not used, it must be connected to an 8,2 kΩ resistor. One or more sensors can be connected to sensor input O or C. For this purpose, the individual sensors are connected in series according to figure 2. Up to five sensors ma�� be connected in series, whereb�� the total cable length must not exceed 25 m. The length of one sensor ma�� be up to 25 m. Before connecting the sensors that are connected in series, it is recommended that the resistance value of the arrangement be measured. The resistance must be 8.2 kΩ ± 500 Ω when the SCE is inactive and must not exceed 500 Ω when it is active. O 2 7.5 Connecting the control circuits The control circuit to be monitored for the opening movement (stop-opening movement) is to be connected to the Stop Opening terminal pair; for the closing movement (stop closing movement), the appropriate control circuit is to be connected to the Stop Closing terminal pair . The connection for the control circuits is permitted onl�� for switching low voltages. The control circuits are dependent on the rated current to protect with an appropriate fuse or the rated current to the control circuits must be limited b�� other measures to the maximum value.

Commissioning / functional test 2 The gate s��stem must be tested for proper function after all of the electrical connections have been established and the suppl�� voltage has been turned on. To do this, activate each of the safet�� contact edges one after another and check the corresponding reactions of the switching unit. 2 2
10. Error diagnosis Onl�� the green LED ma�� illuminate if the suppl�� voltage has been correctl�� connected. If one of the red LEDs illuminate, there is an error in the s��stem which can be pinpointed with the aid of the LED. LED Error Error correction LEDs are not illuminated A single red LED is illuminated Both of the red Transmit LEDs are illuminated The suppl�� voltage is missing, too low or has been connected incorrectl�� Contact edge(s) not connected, connected incorrectl�� or fault�� One of the contact edge connections is not being used The transmission line is fault�� or has been installed incorrectl�� Contact edge(s) not connected, connected incorrectl�� or fault�� Check connections and suppl�� voltage: - 24 V AC/DC at terminal 24 V AC/DC or - 230 V AC at terminals L1 and N Tolerance range: ±10% - Check the connections of the corresponding contact edge (squeezed or brittle suppl�� lines, etc.) - Check safet�� contact edge(s)* An�� contact edge connections that are not being used must be permanentl�� bridged using one of the supplied 8.2 kΩ resistors - Observe the mech. assembl�� instructions (ISK safet�� transmission s��stem) - Check transmission coil cores for abrasion. - Check cable loop; make certain that both transmission coil cores are in the cable loop - Check cable / gate leaf contact points. - Check suppl�� voltage** - Check the connections of the corresponding contact edge (squeezed or brittle suppl�� lines, etc.) - Check safet�� contact edge(s)* * If the error is not related to the s��stem’s wiring, the proper function of the electronics can be tested b�� connecting an 8.2 kΩ resistor to each of the SCE inputs on the ISK 74-31 electronic evaluation s��stem (terminals Stationary Opening or Closing) and to the travelling coil core (connections O and C). If the electronics work perfectl�� after performing the test, the safet�� contact edges must be checked using an ohmmeter. To do this, the respective connection on the SCE for the electronic evaluation s��stem or for the travelling coil core must be disconnected and connected to an ohmmeter. The resistance must be 8.2 kΩ ±500 Ω when the safet�� contact edge is inactive and must not exceed 500 Ω when it is active. ** If both of the LEDs for the travelling SCEs (Transmit Opening and Transmit Closing) illuminate, there is an error in the inductive signal transmission s��stem. The most frequent causes of these errors are bad coil core connections, incorrectl�� installed cable s��stem components (see IKS safet�� transmission s��stem assembl�� instructions) or an impermissibl�� low suppl�� voltage. The maximum resistance value of the cable loop must not exceed 3 Ω. The resistance value can be measured b�� disconnecting the steel cable from the ground terminal and then measuring the resistance between the end of the steel cable and ground terminal. English 19
