4.3.2 PD22P Installation
PD22P must be placed either in frame delivered or otherwise in a suspension frame.
All electrical connections are on the rear side.
The power supply is mounted with 0 in pin 14, earth in pin 15 and phase in pin 16.
The communication cable from MC12P is mounted in pin 1-3.
Should the system be operating more than one PD22P, the communication lines are connected
in parallel in pin 1-3 in all units.
Address "1" is the factory setting of PD22P. In case you want to change this setting, please
consult section 1.4 in this manual.
PD22P is now ready to be switched on and to be programmed from the MC12P.

Address "1" is the factory setting of PD22.
If the PD22 is one of several filling stations in a system, none of the stations may have the
same address and it must therefore be changed.
Change of address is performed via a dip-switch placed at the bottom of the PD22. This change
may only be carried out when the machine is turned off at the main isolator.
Addresses between 1 and 16 may be chosen, and Fig. 4.2 shows the various combinations.
