ALARMS

NOTE:

 

Screenshots shown in this manual reflect 

default settings (when applicable).

Alarm Adjustment

Acknowledging/Clearing Alarms

Alarm conditions activate a red LED indicator that 
backlights the ALARM function key. As an option, an 
alarm condition may also be enunciated by an audible 
alarm signal. An alarm is acknowledged by pressing the 
ALARM key. This calls up alarm display screen(s) that 
provide a text message detailing the alarm condition(s). 
After an alarm condition is corrected, the alarm can be 
cleared by pressing the ALARM key for 3 seconds.

Low Temperature Alarm

If the lowest temperature sensor value in a zone is 
below the low temperature setpoint, an alarm will be 
generated for that zone. Additionally, a relay output will 
be actuated from the LC controller to provide remote 
notification of the event.

NOTE:

 This alarm is per zone. If each zone is meant to 

operate within the same alarm parameters, each 

zone will need to be set accordingly.

To adjust the low temperature alarm setpoint:
1.  Press MENU key to go to the Main Menu screen.
2.  Use UP or DOWN keys and ENTER key to enter 

USER password 2000.

3.  Press UP or DOWN keys to scroll to 

Sys Config

; 

press ENTER key.

4.  Press UP or DOWN keys to scroll to 

Zone 1

, 

Zone 2 

or 

Zone 3

; press ENTER key. 

5.  Press UP or DOWN keys to scroll to

 Alarm 

Setpoints A2-9 

(Zone 1),

 Alarm Setpoints A3-9 

(Zone 2) or

 Alarm Setpoints A4-9 

(Zone 3

)

.

6.  Press ENTER key to scroll to the variable labeled 

Low Temp

 (see Figure 13).

7.  Press UP or DOWN keys to adjust setpoint.

To change the direction of the remote notification relay 
output:
1.  Press MENU key to go to the Main Menu screen.
2.  Use UP or DOWN keys and ENTER key to enter 

USER password 2000.

3.  Press UP or DOWN keys to scroll to 

IO Config

; 

press ENTER key.

4.  Press UP or DOWN keys to scroll to

Config C3

.

5.  Press ENTER key to scroll to the variable in the table 

that intersects 

LoTemp

 and 

Dir

 (see Figure 14).

6.  Press UP or DOWN key to change direction.
The low temperature notification relay has dry contacts. 
The 

Dir

, direction, is the position of the relay without 

a low temperature event. 

NO

 is normally open; 

NC

 is 

normally closed. 
When the 

Val

 (value) is 

OFF,

 the relay is not in an alarm 

condition. When the 

Val

 (value) is 

ON,

 the relay is in 

an alarm condition. The relay connections for the low 
indoor temperature alarm are on the LC6000 terminal 
block; see Table 6 on page 34 for terminal block index.

High Temperature Alarm

If the highest temperature sensor value in a zone is 
above the high temperature setpoint, an alarm will be 
generated for that zone. When this alarm is present, 
emergency cooling in this zone will become active.
There are two high temperature alarm setpoints. This 
is the first and there is no remote notification for this 
alarm.

NOTE:

 This alarm is per zone. If each zone is meant to 

operate within the same alarm parameters, each 

zone will need to be set accordingly.

To adjust the high temperature alarm setpoint:
1.  Press MENU key to go to the Main Menu screen.
