Function description
The contact expansion module is an add­on device without delay­on de­energisation, and it
is used to expand a safety circuit. The contact expansion module is driven by a base unit
(e. g. emergency stop relay).
} Functional procedure after closing the safety contacts of the base unit:
– The supply voltage is present at the input (A1) of the contact expansion module.
– Close the safety contacts 13­14, 23­24, 33­34 and 43­44.
– The LEDs "CH. 1" and "CH. 2" are lit.
} Functional procedure after opening the safety contacts of the base unit:
– There is not supply voltage at input (A1) of the contact expansion module.
– Open the safety contacts 13­14, 23­24, 33­34 and 43­44.
– The LEDs "CH. 1" and "CH. 2" go out.
