3.2.3 Controls Breaker
There is a small pop-out breaker protecting the control system components. This isn’t used during normal operation. If it
were to pop out, try pressing it back in. If it fails to stay in, there may be failure in one of the controls which is shorted, or
is drawing excessive current. This would likely indicate the need for an RMA repair. Contact Marway support.
3.3 EPO Controls
All Optima 533 PDUs include the controls to interface to Marway’s Commander UCP 5000 Remote On/Off/EPO panels
and similar compatible panels. This panel is not required to operate the PDU.
3.3.1 Remote Mode Switch
The
Outlet Control Bus
has a three-mode switch which is used as a local override to the overall remote command
system. The three modes are labeled
Local/On
,
Off
, and
Remote
.
When there is not a remote control panel connected:
•
Local/On
(up position) is the normal operating mode.
•
Off
(center position) causes an internal contactor to disengage power from all branches except for the CB1/J1 branch
which continues to be powered. Therefore,
Off
disconnects power to almost all outlets even if the breakers are
switched on.
•
Remote
(up position) will behave like
Off
.
When there is a remote panel connected to the PDU:
