INFORMATION
Please note that the PSENvip independently carries out an internal safety
test every 2 minutes, if such a test is not requested within this time by an
external control system through System-Init = 1. The PSENvip switches the
OSSDs off during the safety tests. For this reason you should ensure that
the safety tests are requested by an external control system before these 2
minutes have elapsed. The best time to do this is when the OSSDs are
already switched off due to the position within the press stroke, e.g. at top
dead centre.
INFORMATION
The Power Off input has another function during the system status TEST. It
is used for communication with the programmable safety system. See
"Communication with a programmable safety system" in this section.
