INFORMATION
Please note that the PSENvip independently carries out an inter-
nal 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.
