LLE Controls Test Procedure

See unit schematic for correct wire numbers.
Use the CHECKOUT menu in the Installation
Instructions (ACC-SVN178*-EN) to test the damper
operation and any configured outputs. Only items that
are configured are shown in the Checkout menu.
To Perform Checkout Tests:
1. Scroll to the desired test in the checkout menu
using the and buttons.
2. Press the button to select the item.
3. "RUN?" is displayed.
4. Press to start the test.
5. The unit pauses and then displays "IN PROGRESS".
6. When the test is complete, "DONE" appears.
7. When all parameters have been tested, press
(Menu Up) to end the test (e.g. turn off the relay).
N N o o t t e e s s : :
• The checkout tests can all be performed at
the time of installation or any time during
the operation of the system.
• JADE will be in "set up" mode for the first 60
minutes after powered. If OA sensor or Sylk
Bus device (sensor or actuator) is
disconnected during the set up mode, the
JADE will not alarm that failure. The MA
sensor is a system "critical" sensor, if the
MA sensor is removed during the set up
mode, the JADE will alarm. After 60 minutes
the JADE controller will change to operation
mode and all components removed or failed
will alarm in the operation mode.
• Upon power up (or after a power outage or
brownout), the JADE controller module
begins a 5 minute power up delay before
enabling mechanical cooling.

Compressor Start-Up

1. Attach a set of service gauges onto the suction and
discharge gauge ports for each circuit. Refer to the
refrigerant circuit illustration in the Service Facts.
See, "Cooling Operation," p. 27
instructions.

a. Once each compressor has started, verify that
the rotation is correct. If wired correctly the
suction pressure should drop and the discharge
pressure should rise. If a scroll compressor is
rotating backwards, it will not pump and a loud
rattling sound can be observed.
b. If the electrical phasing is correct, before
condemning a compressor, interchange any two
leads (at the compressor Terminal block) to
34
for startup
check the internal phasing. Refer to the
following illustration for the compressor
terminal/phase identification. Do not allow the
compressor to operate backwards for more than
5 seconds. Operation for a period of time longer
than this will result in compressor damage.
N N o o t t e e : : Copeland ZP scroll compressors for
R410A units use Trane OIL00094.
Compressor types and appropriate oil
charge is listed in the following tables.

2. After the compressor and condenser fan have
started and operated for approximately 30 minutes,
observe the operating pressures. Compare the
operating pressures to the operating pressure curve
in the Service Facts.
3. Check system subcooling. Follow the instruction
listed on the subcooling charging curve in the
Service Facts.
4. Repeat Step 1 through Step 3 for each refrigerant
circuit.
5. To stop the SERVICE TEST, turn the main power
disconnect switch to the "Off" position or proceed
to the next component start-up procedure. Remove
electromechanical test mode connections (if
applicable).

Heating Start-Up

1. Clamp an amp meter around one of 1
power wires at the heater contactor.
2. Verify that the heater stage is operating properly.
3. Clamp an amp meter around one of 2
heater power wires at the heater contactor (if
applicable).
4. Verify that the heater stage is operating properly.
5. To stop the SERVICE TEST, turn the main power
disconnect switch to the "Off" position or proceed
