8. OUTPUT-OK RELAY CONTACT
This relay contact is closed when the input voltage is sufficient and the outputs are not shutdown.

9. ON/OFF AND RESET SIGNAL INPUT
This signal input is galvanically isolated with an integrated optocoupler and works in the same manner as the reset
and ON/OFF button. The ON/OFF function has no safety feature included.
In a failure mode (outputs have shutdown), the outputs can be turned on again by
applying a voltage for more than 1 second.

3mA
In normal mode (outputs have not shutdown), a short (> 50ms) voltage pulse will turn
all outputs ON or OFF.
The unit will be shipped (factory setting) with the outputs turned-on.

10. SYNCHRONIZATION OF MULTIPLE PISA MODULES
If multiple PISA modules are used on the same power supply, it is recommended to connect the sync. bus of all
modules together. If one unit shuts down due to the protection function of the input voltage protection circuit
(safeguard), all other modules will shutdown too. This avoids a false interpretation of which output channel caused
the problem. If the sync. terminals are not linked, the module with the highest safeguard protection voltage level
(caused by tolerances) would shutdown
first regardless whether the failure was
caused by this module or not.
Please note:
If the cause for the shutdown was an over-
current of one individual channel only this
module will shutdown and the other
modules will stay on. In this case the sync.
line has no impact on the other modules.
