Unit settings M99 plate ch 6 9 6 9 ch 6 9 6 9 The selection of the function of BH 59 is done via 4 rotational switches behind the front cover of the unit (see drawing on the left). The switches on the left set processor (ch ) and the switches on the right set processor (ch ). Both processors must have the same setting. On both upper switches () the function is selected, on both lower switches () the number of sensor circuits, control and operation mode and the feed back circiuit option is selected.

Operating Mode Auto start (with function and light curtain) On automatic restart the output contacts are activated when the input condition for the selected function is fulfilled. A start-button is only necessary in cases: - If the function light curtain, safety gate or -hand-safety is combined with. - If a function with feedback circuit is selected and the unit has to be reset after a detected fault without disconnection. Manual start (with function and light curtain) If the unit was deactivated by operating the safety function e.g. by pressing an e- button it only can be reset in manual mode by pressing the start button. After voltage failure the unit has to be reset also with the start button. The button has to be pressed t longer then sec. to allow the unit to energise. Feedback Circuit to Monitor External Contactors If the number of contacts has to be increased or a higher current has to be switched by contactors a feedback circuit with ors can be connected to terminals S4-S4 (see drawing ). This circuit allows to monitor the state of the external contactors. The BH 59 monitors continuously if the state of this input corresponds to the state of K and K. In the case of a fault K and K switch off or do t switch on at all. If the fault is removed, the BH 59 has to be reset with the start button. When operating the unit with feedback circuit the circuit has to be connected to terminal S4 and S4. If one of the functions light curtain, safety gate or -hand-safety is combined with the function always works with manual restart. When manual start is selected, the start button is always connected to terminals S4-S44.

Stop (switch in position ) With switch the maximum number of e- loops is selected. Open (unused) inputs (S_/S_ and S_/S_4) have to be linked with a wire bridge. K and K can only be activated, if all e- buttons are released. The function diagrams show only the action of one e- button. We pretend that the others are closed. When the unit is used with -channel e- loops, it checks the state of the inputs. If both channels have different signals for more then 5 ms the outputs K and K are switched off and the unit gives failure code 7. This failure is stored and can only be reset by disconnecting the auxiliary supply.

Flashing frequence: env.,5 s on,,5 s off, end od the sequence: env. s off. It is possible that the two processors show different failure codes. If a failure is displayed, the relays K and K are switched off. These failures are serious and do t allow further operation of the module. They are indicated only by the LEDs run and / or run of the module. The semiconductor outputs 48 and 58 are both switched off. The module can only be reset by switching the power supply off and on again.
