Effective November 2003 

 

 

4.1  

Function Keys 

4.1.1   UP & DOWN ARROW and MENU 

The UP ARROW, DOWN ARROW and MENU function 
keys, located on the membrane faceplate, are used to the 
program the controller. Refer to Section 6 for programming 
the controller. The UP ARROW and DOWN ARROW keys 
are also used to scroll through the readings found on the 
LCD display (Section 4.3). 

4.1.2   ACK.ALARM & STEP 

The ACK.ALARM key, located on the membrane faceplate, 
is used while programming the controller, either to enter data 
into memory or to acknowledge the current data displayed on 
the screen. 

Depressing the ACK.ALARM key acknowledges all  
alarm conditions (except for Locked Rotor), and resets  
the Common Alarm Relay, 3CR. 

Note that the respective  

alarm LED’s remain lit until the Reset key is pressed. It  
is also used to review the previous 2048 status/alarm 
conditions via the LCD display.  

As well, a duplicate ACK.ALARM black pushbutton and a 
STEP pushbutton are hard wired on the enclosure flange.  

They allow the user to operate the associated functions 
without opening the controller door. The STEP pushbutton 
allows the user to view controller data, one function at  
a time. 

4.1.3   Reset Button 

The RESET key resets all relays and LED’s to their  
original state.  

4.1.4 

 Lamp Test Button 

When pressed and held, the LED’s will illuminate 
sequentially. This function can be utilized at any time  
during the operation of the controller. 

4.1.5   Time/Print Button 

This button toggles between two functions. When initially 
pressed the LCD display will prompt the user to hold the 
button for 3 seconds, at which time an audible tone is heard, 
after which the stored STATUS and ALARM conditions are 
transmitted to the printer. If the print mode is selected for 
auto print, the 

LMR

 automatically downloads the conditions 

to the printer. The auto print mode is particularly helpful 
during setup and testing of the controller. 

When pressed again, the controller will indicate: 

TOP: 

Actual Date & Time 

BOTTOM:   Weekly Test Time 

BOTTOM: 

Quantity of messages stored in memory. 

RIGHT 

NOTE: 

To avoid paper build up inside of the enclosure, it is 

recommended that the Print Mode be selected as Manual 
during normal operation of the controller. 

Refer to Section 6. 

 

4.2  

Annunciators  

All alarm and status indicators are of the LED type and 
located in the top portion of the main display panel. Refer  
to Appendix A, Page 18. 

The LED indicators are color-coded as follows: 

 GREEN: 

Status 

Indicators 

 RED: 

Alarm 

Indicators 

The STATUS LED’s indicate motor running conditions, 
timer status and start demands. 

The ALARM LED’s indicate the alarms as decreed by 
NFPA, Pamphlet 20, in addition to other system and  
external conditions. 

NOTE: For software versions prior to and including V2.4, 
the Common Alarm relay energizes. For V2.5 and greater  
it will de-energize (fail-safe) upon detection of an alarm. 
 
Listed below is a description of each STATUS / ALARM 
condition in the order they appear on the membrane 
faceplate. 

4.2.1   Power On 

This LED will turn on when AC power is detected. 

4.2.2   Pump Running 

The LMR monitors the auxiliary contact of the main RUN 
contactor and upon detecting a contact closure, the PUMP 
RUNNING LED will illuminate. 

4.2.3   Run Period Timer (RPT) 

The RPT LED illuminates during the timing sequence, 
typically set for ten (10) minutes. Refer to Section 6 for 
programming the controller. 

(Not available on Foam Pump Controllers – see section  
15.2 of this manual)  

4.2.4   Sequential Start (Sequence) Timer 

The Sequence Timer LED flashes while timing. Refer to 
Section 6 for programming the controller. 

4.2.5   Local Start 

This LED will illuminate, after the Local Start pushbutton  
is pressed, to indicate the system start demand. 

4.2.6   Remote Start 

This LED will illuminate, after the Remote Start pushbutton 
is pressed, to indicate the system start demand. 

4.2.7   Deluge Valve 

This LED will illuminate, after detection of the Deluge 
Valve contact closure, to indicate the system start demand. 
The Common Alarm relay, 3CR, will de-energize. 

4.2.8 Interlock 

ON 

This LED will flash to indicate that the controller is  
in a locked out mode and is prevented from starting.
