MA-5130-GBR PS20 NON STOP DRUM UNLOADER INHIBITION MANUAL
External channels inhibition
1. If only this signal will be connected, use a 0.5 mm
2
two-wire cable.
2. Open the door of the electrical cabinet as far as possible. Thread the
power cord (Ø4-8 mm) through the electrical cable gland Pg13, making
sure that the cord reaches the terminal blocks where that signal has to
be connected.
3. Disconnect the jumper cables between terminals 13X31 - 13X32
(inhibition 1) and 13X33 - 13X34 (inhibition 2).
4. Insert the wires in 13X31 - 13X32 (inhibition 1) and/or 13X33 - 13X34
(inhibition 2) terminals blocks and tighten them with the fixing screws.
Each signal inhibits the following elements:
The terminal block is double so you must to connect every wire in a
free hole of the terminal block. It has no polarity so it doesn’t matter
the place you connect them.
5. Make sure that the cables are firmly attached by the terminal screws.
6. Make sure that the cable is well connected and that its path through
the electrical cabinet presents no risks of snagging, being cut or any
other accidental deterioration.
Caution: When the external inhibition is activated, it is not possible to activate
(ON) from the programming screen the different elements of the inhibited
channel group.
