outputs (activation of the safety device)
- TAMPER output signalling opening of the power
supply casing
- type OC, 50mA max.
normal status: L level (0 V)
failure status: hi-Z level
- microswitch, NC connectors (closed casing),
0.5A@50 V DC (max.)
Optical signalling:
LED diodes L1÷L4 (green)
LED diode L
AW
(red)
- status of AUX1…AUX4 outputs
normal status = illuminated
failure status = not illuminated
- failure signalling of min. one AUX output
normal status = not illuminated, failure status = illuminated
F fuse
F1÷F4 fuse
T 1A/ 250 V
F 1A/ 250 V or PTC 1A
Mechanical parameters (table 4).
