1-2 Power supply, 12-30VDC/VAC
3-4 First input, 8k2 resistive safety edge
5-6 Second input, 8k2 resistive safety edge
Self-tested output* regarding the first input of the resistive safety edge.
7-8 Normally closed contact (N.C.) with powered card and pressure-sensitive safety edge at rest. The con-
tact is opened when an obstacle activates the safety edge or in case power is cut off to the device
Self-tested output* regarding the second input of the resistive safety edge.
9-10 Normally closed contact (N.C.) with powered card and pressure-sensitive safety edge at rest. The con-
tact is opened when an obstacle activates the safety edge or in case power is cut off to the device
*Self-testing of outputs:
The SC.EN card has been specially designed to comply with regulations in force. Through a series of redundant
self-testing, in fact, the microprocessor is always able to monitor the correct operation of the device.
In addition, each single output of the card is controlled by 2 relays. At each activation of the resistive safety
edge (or in case of power failure), the related output contact is opened and, upon recovery of the edge correct
operation (or when power is reset), the card performs a self-testing on each single relay to check its correct
operation. If one of the relays is blocked or not operating, the test outcome will be negative and the output
contact will be kept open by the second relay.
The extractable terminal board facilitates connections.
Figure 3 shows a wire diagram of possible connections to the SC.EN interface.
