5.1 TECHNICIAN CONFIGURATION/ TEST
MODES (REMOVE JUMPER MODE)
The Technicians Configuration/Test Mode allows the
technician to change Configurations, test the unit
components and/or service the refrigeration system.
To place the microprocessor in the Technicians Con-
figuration/Test Mode using the technician interface
connector assembly (see Figure 5-1):
1. Place the SROS in the OFF position.
2. Locate the technician interface connector, remove
the protective plug to gain access to the wire termi-
nals.
3. Plug in connector assembly.
4. Place the SROS in the START/RUN position. The
ALARM LED will come on, the setpoint will appear,
but the refrigerated compartment Temperature will
not, and "REMOVE JUMPER" will appear in
the MessageCenter for 10 seconds. Remove the
technician interface connector assembly at this time.

5.1.2 Component Test Mode
WARNING
If the unit is in Standby Operation and
powered, voltage will be applied to high
voltage components (i.e. the fan motor
contactor) and those components will op-
erate (i.e. the fan blades will turn) when
those components are energized using
component test mode.
Component Test Mode allows the Technician to ener-
gize individual circuits for 5 minutes at a time. The
engine is not allowed to start when the Micro is in
Component Test Mode. To enter the Component Test
Mode:
a. Enter the Technicians Configuration/Test Mode
(refer to Section 5.1) and select COMPONENT
TEST MODE. When "

TO SCROLL, THEN = TO
SELECT" appears in the MessageCenter:
b. Press the UP ARROW Key to scroll through the
component list beginning at the top.
Press the DOWN ARROW Key to scroll through the
component list beginning at the bottom.
c. Press = to select the component you wish to test.
For example, if Buzzer is selected, the buzzer will
come on, and "BUZZER OFF IN 5 MINUTES" will
appear in the MessageCenter. The minutes will
count down to 0 at which time the buzzer circuit will
be de-energized, and the MessageCenter will dis-
play the last component tested.
Should you need more than 5 minutes, the timer
may be reset to 5 minutes anytime during the test by
