Inputs 4- Funktion_Geraete_Empfaenger_Eingaenge_1_P  System-Init
Input whose signal comes from the safety system PSS 4000.
System-Init = 1: Press at top dead centre or in an upward movement
System-Init = 0: Downward movement
The PSENvip can perform internal availability tests and completely
activate the protected field when System-Init = 1. The outputs OSSD
and mute are in the OFF state (OSSD = 0, Mute = 0).

Funktion_Geraete_Empfaenger_Eingaenge_3  Power Off
Input signalling that the press brake is in setup mode.
Power Off = 1: Setup mode activated
All safety functions are deactivated in setup mode.
– The display is switched on.
– The OSSD LED on the receiver lights up red.
– The light source is switched off.
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.
INFORMATION
The Power Off input has another function during the system sta-
tus TEST. It is used for communication with the safety system.
See "Communication with a safety system" in this section.
