Power supply of the VT-DFPD pilot valve
The pilot valve VT-DFPD is supplied with 24 V DC voltage. If this voltage supply is
not provided on the part of the system, power supply unit
VT-NE30-2X/ according to RE 29929 can be used. The 24 V supply of the power
supply unit is to be connected to connections 1 (+24 V) and 2 (L0) of the mating
connector.
In the case of the connection cable optionally available, this refers to the 2 black
wires of the 3-pin cables with a cross-section of 1 mm². Connect the wire marked
with "1" to +24 V and the wire marked with "2" to L0 (ground). Connect the
yellow/green wire to ground.
