Relay Operation Details 

Overview 

The relay capabilities of the meter expand its usefulness beyond simple indication to provide users with 

alarm and control functions. These capabilities include front panel alarm status LEDs as well as either 2 

or 4 optional internal relays. Typical applications include high or low temperature, level, pressure or flow 

alarms, control applications such as simple on/off pump control, pump alternation control for up to 4 

pumps, and basic batch control. There are four basic ways the relays can be used: 
1.  High or Low Alarms with Latching or Non-Latching Relays 
2.  Simple On/Off Control with 100% Adjustable Deadband

 

3.  Sampling (Based on Time) 
4.  Pump Alternation Control for up to 4 Pumps 

Relays Auto Initialization 

When power is applied to the 

meter, the front panel LEDs and 

alarm relays will reflect the state of 

the input to the meter. The 

following table indicates how the 

alarm LEDs and relays will react on 

power-up based on the set and 

reset points: 

Fail-Safe Operation 

The following table indicates 

how the relays behave based 

on the fail-safe selection for 

each relay: 

Note: NO = Normally Open, 

NC = Normally Closed. This 

refers to the condition of the 

relay contacts when the power to the meter is off. 

Front Panel LEDs 

The LEDs on the front panel provide status indication for the following: 
The meter is supplied with four alarm points that include front 

panel LEDs to indicate alarm conditions. This standard feature 

is particularly useful for alarm applications that require visual-

only indication. The LEDs are controlled by the set and reset 

points programmed by the user. When the display reaches a 

set point for a high or low alarm, the corresponding alarm LED will turn on. When the display returns to 

the reset point the LED will go off. The front panel LEDs respond differently for latching and non-latching 

relays. 
For non-latching relays, the LED is always off during normal condition and always on during alarm 

condition, regardless of the state of the relay (e.g. Relay acknowledged after alarm condition). 
For latching relays, the alarm LEDs reflect the status of the relays, regardless of the alarm condition. The 

following tables illustrate how the alarm LEDs function in relation to the relays and the acknowledge 

button (Default: F3 key assigned to ACK):
