Voltage Test Jacks
The controller front panel display has three test jacks that allow you to measure the system output voltage
with a hand-held meter. The jacks are referenced with C (Common), V1 (Voltage One), and V2 (Voltage Two)
or Common, Plant, and Converter. The voltage references correspond to the voltage referenced on the
default front panel screen. For product consistency, factory built systems connect the controller in a manner
such that V1 provides access to the +24V DC bus and V2 provides access to the -48V DC bus.
Thus, one system voltage can be measured between C and V1 and
a second output voltage can be measured between C and V2. A
voltage will not be present on one of the voltage test jacks if the
controller resides in only a single voltage system without
converters.
