The auto diagnostic system considers any
system status other than normal as a
problem.
Before taking any action, note down the
messages displayed on the control panel.
Certain problems may prevent the control
panel from functioning.
In this case, it is strongly recommend-
ed to call the MGE UPS SYSTEMS after-
sales support department.
■ If the load is still correctly supplied with
power, it has probably been transferred to
the bypass AC source (static bypass) and
is therefore no longer protected (if the sys-
tem is in on-line mode);
■ if the load is no longer supplied with
power, transfer it manually to the mainte-
nance bypass (see section below).
maintenance bypass
This operation is possible only if the sys-
tem includes a bypass AC source. It
results in the load being directly supplied
by the bypass AC source via maintenance
bypass switch Q3BP, thus ensuring a
higher level of security in the event of a
malfunction.
Switching procedures are explained on
drawings next to each switch in the UPS
cabinet and the external bypass unit. See
section "maintenance configuration".
