Compressor Setup
# of stages:2
Minimum ON:030s
Minimum OFF:180s
THIS SCREEN DISPLAYS THE NUMBER OF STAGES PROVIDED WITH THE UNIT AND
SHOWS THE COMPRESSOR MINIMUM ON AND OFF TIMES (IN SECONDS).
This screen only appears if DX cooling was provided with the unit.
The purpose of having minimum ON/OFF times is to prevent the compressor from short
cycling.
Do not change the defaults shown without consulting the factory.
Compressor Setup
Between stages:240s
Lead-Lag:YES
Lead-Lag Time:100hrs
THIS SCREEN DISPLAYS THE DELAY TIME BETWEEN STAGES, ALONG WITH THE
LEAD-LAG TIME PROGRAMMED FOR THE COMPRESSORS.
This screen only appears if 2-stage DX cooling (2 compressors) was provided with
the unit.
Between Stages is the time delay (in seconds) between the first and second
compressors engaging. Lead-Lag governs whether the stages will reverse operation
order after some period of time designated by the Lead-Lag Time setting (Factory
Default: YES, 100hrs.). The Lead-Lag Time is the duration of time the unit will operate
before reversing the DX staging. In other words, based on the factory default,
Compressor 1 will engage before Compressor 2 for 100 hours of operation. After 100
hours, the order reverses and Compressor 2 will engage first. This cycle will continue
indefinitely.
Stage1:ON@050%OFF00%
Stage2:ON@100%OFF50%
THIS SCREEN SHOWS WHEN EACH COMPRESSOR IN A SINGLE OR TWO STAGE DX
UNIT WILL ENGAGE AND DISENGAGE.
This screen only appears if DX cooling was provided with the unit.
Each compressor will engage and disengage based upon the percentage of
cooling that the user inputs (refer to Cooling Loop Override screen on the ‘MANUAL
OVERRIDE’ menu).
Lead-Lag Note
Stage:12
Compressor Lead:12
Compress Lag:21
THIS SCREEN ALLOWS FOR ADJUSTMENTS TO BE MADE TO THE ORDER OF WHICH
COMPRESSORS WILL ENGAGE.
This screen only appears if 2-stage DX cooling was provided with the unit.
This screen shows the order in which the compressors will engage when operating in
the lead-lag setup.
Compressor will lockout if
safety switches (ID8) trip
3 times in:120 min
IF THE CONTROLLER DETECTS THREE (3) ALARMS IN THE TIME PERIOD SHOWN, IT
WILL SHUT OFF THE COMPRESSORS AS A SAFETY MEASURE.
This screen only appears if DX cooling was provided with the unit.
The safety lockout screen monitors the safety loop of the DX system, including high
limit, low limit, and ambient temps. If the controller detects three (3) trips within 120
minutes, the controller will shut down the DX system. (Example: If the low limit switch
trips, automatically resets, and then trips two more times within 120 minutes, the DX
system will shut down). If there is a fatal trip, such as a high limit pressure switch trip,
the DX system will not run and the controller will signal an alarm after trying three times
unsucessfully to start the DX cooling process.
Heater Controller
Integration:300s
Band:20ºF
THIS SCREEN DISPLAYS THE INTEGRATION TIME FOR THE PI CONTROL OF THE
HEATING MODE AND THE TEMPERATURE BAND AROUND THE SUPPLY SET POINT.
This screen only appears if a Heating option was provided with the unit.
This controller uses a Proportional + Integral type control. The integration time
programmed into the controller is to provide a smooth reaction to conditions, allowing
for less sporadic changes in discharge temperature. To speed up reaction time,
decrease the integration time. For slower reaction time, increase the integration time.
When making adjustments, make them in small increments, and test the system to
determine if the new setting is adequate prior to further adjustment. The band is the
range that the integration will occur between.
Range of Integration = Supply set pt ± Band. ie: 50° F ± 20° F
