MAX. AND MIN. READINGS (PEAKS) 

 

To display the peak values of Process variable push Peak key once and let go. The display will first indicate 
‘HIGH   Pt’ briefly and then the value of the highest Process variable value monitored by the system. A 
second push while high peak is being displayed will bring up low peak value on the display. The value will 
be preceeded by the message ‘LO  PT’.. 
 

 
To reset the peaks to the present value of Process Variable simply push the PEAK key once and keep it 
pushed. The display will briefly indicate ‘HIGH   Pt’ and then the value of the high peak. With the PEAK  
key  still pushed, go on to press the RESET key. On resetting the display will indicate the new value of high 
peak. To reset the low peak value, get the system in low peak display mode. This is done by pushing the 
PEAK key twice. Do not release the PEAK key after the second push. While keeping the PEAK key pushed, 
press the RESET key. This will reset the low peak to current Process Variable value. 
 
 

RATE 

 
The DP3600 unit keeps track of the rate of process change and can be displayed by pushing the key labeled 
‘RATE’. The display first reads 'RATE' followed by the rate value that was monitored over the last time 
base. The maximum rate of change displayable is equal to the value of High Scale. If the calculated rate is 
negative, it will be indicated so by a negative sign. Rate time base, which is in seconds, is programmable 
and is set during SETUP of the unit. 
 
 
 

TIME 

 

 
The system keeps track of the process run time in hours, minutes and seconds. The display format is 
HH.MM.SS (HH = Hours, MM = Minutes, SS = Seconds). To display the elapsed time since the system 
was turned on or  last reset, push the TIME key. The display will first read 'ELPSd t' (for ELAPSED 
TIME) and then the value of elapsed time. 
 

 
To reset the timing and start it all over again, first push the TIME key and while keeping it pushed press the 
‘RESET’ key. The time will reset and the display will read ‘RESET’ following which the unit will start 
tracking time from zero. 
 
NOTE: On resetting, the time relays, if energized, will de-energize and would be activated again when the 
programmed amount of time has elapsed.
