Internal Relay Cabinet Controls
In addition to front panel controls, your Z-MAX cabinets have two different types of
internal override switches for the relays:
•
Master Override
•
Relay Override
Master Override
See the figure below for the location of the master override. The master override has
three modes of operation:
•
Normal - Allows the Control Module and inputs to control the state of the relays
•
All ON - Forces all of the relays to the ON state and
the Control Module and
inputs can not turn the relays Off
•
All OFF - Forces all of the relays to the OFF state and
the Control Module and
inputs can not turn the relays On
The inside of a relay cabinet, when energized,
can be DANGEROUS as HIGH VOLTAGES are
present. Fatal accidents are possible. Only trained
authorized personnel should have and gain access
to the internal workings of your relay panel,
access is not required for any normal
configuration or operational purpose.
