SHUTDOWN
1 De-energize the load.

assure a thorough cool down of all
load elements (optional).

Power” button.
4. Press the “Release Remote” button.
LOAD DUMP
This Load Bank contains a Load Dump
feature which de-energizes all applied
load when customer supplied contacts
open. Normally closed to run, they are
rated at 2A @ 24VDC and should be
wired to TB‘LD’ 1–2. When these con-
tacts open all applied load will be de-
energized and the load section will be
disabled. If desired, the customer may
install automatic transfer switch con-
tacts, a manual pushbutton or circuit
breaker for this use.
The operator also has the option of
bypassing these contacts and enabling
the load section by flipping the “Auto
Load Dump” switch to the “Bypass”
position. This disables the load dump
feature and illuminates the “Load Dump
Bypass” lamp.
Metering Screen
Do Not allow the Load Bank to
operate unattended for extended
periods.
FAILURE DETECTION
If a “Failure” occurs the corresponding
lamp will illuminate and the load will be
de-energized. Before reapplying a load,
the failure must be corrected and the
system must be reset by turning the
Load Bank “Off” then “On”.
This is a permissive/energize-to-run cir-
cuit in which all safety sensors must
energize their control relays on normal
operation before load can be applied.
This system includes the following com-
ponents:
1. Exhaust Temperature Switches
(EXTS1–EXTS4)
2. Pressure Switch (PS)
3. Intake Temperature Switch (INTS)
Thermocouple
Temperature Switch
The exhaust temperature network con-
sists of a type J thermocouple (TC) and
a solid state thermocouple sensor
(EXTS). The temperature switch has
been factory adjusted for precise Load
Bank over temperature protection un-
der normal operating conditions. Un-
usual operating conditions may require
