ALARMS

Alarms inform the user that there is an operational problem with

the unit. Some alarms will result in the unit shutting down, some

will shut down only the affected equipment, and some are infor

-

mational only. The 100 most recent alarms (active or cleared)

can  be  viewed  on  the Alarm  Status  screen  on  the  Equipment

Touch device.

Alarm Status

When an alarm is active, the alarm icon (exclamation mark) back

-

ground on the Home screen is red to indicate an alarm condition.

See Fig. 62. 

Fig. 62 —  Alarm Icon

To access the alarm information, press the red alarm icon on the

Home page touchscreen. Press the alarm icon twice to access the

Alarms Screen options. See Fig. 63.

Fig. 63 —  Alarms Screen

CLEARING ALARMS

When an alarm event occurs, an audible alarm (touchscreen setup

option) will sound and the Equipment Touch will log the event on

the Active Alarms.  Press  the  alarm  icon  to  display  the  active

alarms list. To access the menu page, press the alarm icon again.

Press Clear Active alarms to reset alarms. See Fig. 63.

The alarm will remain active until it is cleared. If the alarm is an

automatically re-settable alarm, it will be cleared as soon as the

condition which initiated it is corrected. To clear an active alarm

press Clear Active.

If an alarm is automatically cleared, it will be removed from the

Active Alarms section and moved to the Returned-to-Normal sec

-

tion. If the alarm is manually cleared it will be moved to the Man

-

ually Cleared section. Refresh the screen by pressing the Reset

Alarms button on the Home screen.

Alarm Matrix

Table 9 lists the possible alarm events which can be displayed in

the Alarm Status screen of the Equipment Touch and Table 10 lists

the condition/mode statuses which might be displayed to indicate

the Alarm condition/mode of the unit. These are classified as auto

-

matically and manually re-settable alarms.

AUTOMATIC RESET

These alarms are reset automatically after the condition which ini

-

tiated the alarm is corrected. Then they will show up under the Re

-

turn-to-Normal section of the history. Refresh the screen to see the

change. If the condition which initiated the alarm is not corrected,

the alarm will be reissued. Table 9 lists the automatic reset alarms.

MANUAL RESET

These alarms are reset manually from the Equipment Touch (see

“Clearing Alarms”) or after cycling the power on the OEM. Then

they will show up under the “Returned-to-Normal” section of the

history.  In  which  case  they  will  show  up  under  the  “Manually

Cleared” section of the history. If the condition which initiated the

alarm is not corrected, the alarm will be reissued. Table 10 lists the

manual reset alarms.

ALARMS AFTER STARTUP

Alarms may occur after startup due to a variety of factors. Always

check that all sensors and inputs are properly connected.

SAFETY SWITCHES

• High Pressure Switch (HPS1): If HPS1 is open, compres

-

sor #1 will turn off and the OEM controller will issue an

alarm. After  manually  resetting  HPS1,  the  HPS1  alarm

will reset. Following a minimum time off delay, compres

-

sor #1 will turn on. If the OEM controller records 3 high

pressure start/restart failure incidents within 1 hour, com

-

pressor #1 is locked out and the OEM controller will issue

an  alarm.  The  compressor  lock-out  can  be  reset  in  the

Equipment  Touch  or  by  cycling  the  power  of  the  OEM

controller. Refer to the Installation, Operation and Mainte

-

nance (IOM) Instructions for more information.

NOTE: For systems with two circuits, this is the same for

compressor #2, Y2 and HPS2.

• Low  Pressure  Switch  (LPS1):  If  LPS1  is  open  after  the

LPS1 by-pass time, the OEM controller will issue an alarm

and compressor #1 turns off. After 30 seconds (fixed), the

LPS1 alarm  will  reset.  Following  the  minimum  time-off

delay, the compressor #1 will turn on. If the OEM control

-

ler  records  3  low  pressure  start/restart  failure  incidents

within 1 hour, compressor #1 is locked out and the OEM

controller  will  issue  an  alarm.  The  compressor  lock-out

can  be  reset  in  the  Equipment  Touch  or  by  cycling  the

power of the OEM controller. Refer to the IOM for more

information.

Note: For systems with two circuits, this is the same for

compressor #2, Y2 and LPS2.

SAFETY SHUTDOWN

• Smoke Detector (Optional): When a smoke detector (SD)

is provided, it is wired directly to the OEM controller. If

smoke is detected, the OEM controller will shut down the

unit. The alarm can be reset in the Equipment Touch or by

cycling the power of the OEM controller.

• High pressure switch lockout: A compressor fails to start 3

times in an hour due to high pressure switch lock out. The

alarm can be reset in the Equipment Touch or by cycling

the power of the OEM controller.

• Low pressure switch lockout: A compressor fails to start 3

times in an hour due to low pressure switch lock out. The

alarm can be reset in the Equipment Touch or by cycling

the power of the OEM controller.

• DX LAT or suction line temperature lock out: A compres

-

sor fails to start 3 times in an hour due to DX LAT or suc

-

tion line temperature lock out. The alarm can be reset in

the Equipment Touch or by cycling the power of the OEM

controller.

• SAT  sensor  failure: The OEM  controller  detects an  SAT

sensor  failure. The  alarm  can  be  reset  in  the  Equipment

Touch or by cycling the power of the OEM controller.
