Table 4-13  Analog Output Prompts (continued) 

MIN ON TIME 

 

 

 

OFF or 

≥

 0 

The minimum on time (in seconds) for the output.  If the input 
source calls for the output to be on for less than this time, the 
output will not turn on at all. 

Example 1 

Impulse Time = 100.  Min On Time = 5 seconds.  The output 
will not come on unless the input source is 

≥

 5%.  For 

instance, if input source = 3%, output would be on for 3% of 
impulse time, or 3 seconds, but since 3 seconds is less than 
the Min On Time, output will not turn on. 

Example 2 

Impulse Time = 150.  Min On Time = 3 seconds.  The output 
will not come on unless the input source is 

≥

 2%.  For 

instance, if input source = 1%, output would be on for 1% of 
impulse time, or 1.5 seconds, but since 1.5 seconds is less 
than the Min On Time, output will not turn on. 

MIN OFF TIME 

 

 

 

OFF or number 

The minimum off time (in seconds) for the output.  If the input 
source calls for the output to be off for less than this time, the 
output will not turn off at all. 

Example 1 

Impulse Time = 100.  Min Off Time = 5 seconds.  The output 
will not turn off unless the input source is 

≤

 95%.  For 

instance, if input source = 98%, output would be off for 2% of 
impulse time, or 2 seconds, but since 2 seconds is less than 
Min Off Time, output will not turn off. 

Example 2 

Impulse Time = 150.  Min Off Time = 3 seconds.  The output 
will not turn off unless the input source is 

≤

 98%.  For 

instance, if input source = 99%, output would be off for 1% of 
impulse time, or 1.5 seconds, but since 1.5 seconds is less 
than the Min Off Time, output will not turn off. 

OUTPUT RELAY 

Select discrete output 
channel. 

This is the discrete output channel if using DAT output 
algorithm.  This discrete output will be unprogrammable 
under the PROGRAM DISCRETE OUTPUTS programming 
menu. Only discrete outputs 1 though 5 will be programable 
on any of the installed discrete output cards. Programming of 
discrete output 6 is not allowed. 

 

ATTENTION 

ON/OFF loop types provide direct output without the use of an analog output.  To complete an ON/OFF loop 
configuration, assign the ON/OFF loop’s output (LPn OS) to a Discrete Output Relay. (see Program Discrete Outputs, 
section 4.11).
