Clock Set Mode — The Clock Set mode is used for setting

the date and time for the internal clock of the VFD. In order

to use the timer functions of the VFD control, the internal

clock must be set. The date is used to determine weekdays

and is visible in the fault logs.

1. Select MENU (SOFT KEY 2). The Main menu will be

displayed.

2. Use the UP or DOWN keys to highlight CLOCK SET on

the display screen and press ENTER (SOFT KEY 2). The

clock set parameter list will be displayed.

3. Use the UP or DOWN keys to highlight CLOCK VISI-

BILITY and press SEL (SOFT KEY 2). This parameter

is used to display or hide the clock on the screen. Use the

UP or DOWN keys to change parameter setting. Press

OK (SOFT KEY 2) to save the configuration and return

to the Clock Set menu.

4. Use the UP or DOWN keys to highlight SET TIME and

press SEL (SOFT KEY 2). Use the UP or DOWN keys to

change the hours and minutes. Press OK (SOFT KEY 2)

to save the configuration and return to the Clock Set

menu.

5. Use the UP or DOWN keys to highlight TIME FORMAT

and press SEL (SOFT KEY 2). Use the UP and DOWN

keys to change the parameter setting. Press OK (SOFT

KEY 2) to save the configuration and return to the Clock

Set menu.

6. Use the UP or DOWN keys to highlight SET DATE and

press SEL (SOFT KEY 2). Use the UP or DOWN keys to

change the day, month, and year. Press OK (SOFT KEY

2) to save the configuration and return to the Clock Set

menu.

7. Use the UP or DOWN keys to highlight DATE FOR-

MAT and press SEL (SOFT KEY 2). Use the UP or

DOWN keys to change the parameter setting. Press OK

(SOFT KEY 2) to save the configuration and return to the

Clock Set menu.

8. Press EXIT (SOFT KEY 1) twice to return to the main

menu.

I/O Settings Mode — The I/O Settings mode is used for

viewing and editing the I/O settings.

To configure the I/O settings, perform the following

procedure:

1. Select MENU (SOFT KEY 2). The Main menu will be

displayed.

2. Use the UP or DOWN keys to highlight I/O SETTINGS

on the display screen and press ENTER (SOFT KEY 2).

The I/O Settings parameter list will be displayed.

3. Use the UP or DOWN keys to highlight the desired I/O

setting and press SEL (SOFT KEY 2).

4. Use the UP or DOWN keys to select the parameter to

view. Press OK (SOFT KEY 2).

5. Use the UP or DOWN keys to change the parameter set-

ting. Press SAVE (SOFT KEY 2) to save the configura-

tion. Press CANCEL (SOFT KEY 1) to keep the previ-

ous value. Any modifications that are not saved will not

be changed.

6. Press EXIT (SOFT KEY 1) twice to return to the main

menu.

START-UP

General — 

Complete the start up checklist on page CL-1

before attempting system start-up.

Confirm that compressor suction and discharge service

valves are OPEN. 

Wait 24 hours before starting the compres-

sors to permit warming by the crankcase heaters.

AFTER 24 hours

, continue with the procedures below.

Confirm the Input Power Phase Sequence — 

The

input power phase rotation sequence must be L1-L2-L3 =

ABC (or forward or clockwise) as indicated with a phase

rotation meter. Incorrect input phase rotation will cause the

compressors to rotate in reverse, which results in no cooling

capacity. 

If the compressor is rotating the wrong direction, it may:

emit increased noise; shut down due to internal overload pro-

tection; have only a small decrease in suction pressure when it

starts; or have only a small increase in discharge pressure when

it starts. Also, no cooling will be produced at the evaporator. If

any of these conditions occur, refer to the Installation and Ser-

vice Instructions to correct the compressor rotation before con-

tinuing.
PHASE/VOLTAGE MONITOR

 

(OPTION)

1. Measure the input voltage at the main power terminal

block (TB1).

2. If the measured voltage does not match the indicated volt-

age on the voltage monitor adjustment knob, disconnect

unit power. Rotate the voltage adjustment knob on the

face of the monitor to match the measured voltage. Re-

connect unit power.

Water Fill and Air Purge — 

If present, water and

steam valves should be opened to fill the unit piping and heat

exchangers. Controlled valves may require a manual override

of control actuators or manual override of the control signal

outputs from the unit control panel or building management

system. Refer to the 50XJ Installation and Service Instructions.

To remove air from the internal piping and heat exchangers,

use the plug ports provided. On the condensers, use the

condenser air vent (bleed valve) in the left side of the fan

compartment (Fig. 10). On the water economizer coil (if pres-

ent), the plug is on top of the supply header and return header,

at the same end as the water connections. On the hot water coil

(if present), the plug is on the top of the return header at the op-

posite end as the water connections. On the steam coil (if pres-

ent), the plug is on the top of the supply header at the same end

as the steam connections.
NOTE: Failure to remove air trapped in the heat exchangers

will result in reduced capacity and/or may initiate system

protection devices.

IMPORTANT: Fan rotation direction can NOT be

used for the phase sequence check; fan rotation for

VAV units with a variable speed drive is independent

of the unit input wiring sequence.

CAUTION

Avoid subjecting the condensers to thermal shock,

excessive pressures and temperatures. These conditions

can impose stress on the condenser, resulting in premature

failure of the heat exchanger as well as other system

components. DO NOT add hot fluid to the unit when it is

cold, or cold fluid when the unit is hot.
