Trident load banks are protected by four types of sensors.
1. Intake temperature, which checks the incoming air to ensure
the load elements can be adequately cooled.
2. Exhaust temperature, which checks the temperature of the air
coming out the load bank to ensure the load elements are
being adequately cooled.
3. Fan pressure, when ensures the fan blades are forcing air into
the load element chamber.
4. Fan current, which ensures the fan motor isn't overloaded or
jammed.
If the Trident regis-
ters an alarm, the green
"Normal Operation"
indicator on the main
screen will change to a
red "Load Bank Failure"
notification and the unit
will dump the load. De-
tails about the alarm can
be found on the Mainte-
nance screen, accessible
by pressing the "Mainte-
nance Mode" button.
The Trident
bank's HMI can alert
you to four alarms:
• Load Bank Failure:
Indicates that there
is a problem with the
load bank that must
be resolved immedi-
ately.
• Exhaust Temp. Fail-
ure: Air leaving the load bank is too hot.
• Fan Failure: Either the fan is not pushing cooling air into the
®
element chamber or the fan motor is overloaded.
