DATA ALARM PROCESSOR-III (DAP-III)
CONTROL LOGIC
PROCESSOR SELF-TEST
Whenever the DAP-III is turned on, it performs a Diagnostic Self-Test of the following:
MODEL nnn-nnn-nnn BOOTLOADER REV: n:nn
MODEL nnn-nnn-nnn SOFTWARE REV: n.nn
MODEL nnn-nnn-nnn CONTROL MODULE: REV Nnn.n
MODEL nnn-nnn-nnn EXPANSION MODULE REV. nn.n*
MODEL nnn-nnn-nnn RELAY MODULE REV. nn.n*
MODEL nnn-nnn-nnn ANALOG MODULE REV nn.n*
MODEL nnn-nnn-nnn ETHERNET MODULE REV. nn.n*
(
Can vary based on Comm Card installed.)
FLASH:
PASS OR FAIL
STATIC RAM:
PASS OR FAIL
PARAMETERS:
PASS OR FAIL
RAM SIGNATURE:
PASS OR FAIL
ANALOG:
PASS OR FAIL
12 VDC REGULATED:
PASS OR FAIL
5 VDC REGULATED:
PASS OR FAIL
BATTERY VOLTAGE:
PASS OR FAIL
RETURN TEMP SENSOR:
PASS OR FAIL
DISCHARGE TEMP SENSOR:
PASS OR FAIL
HUMIDITY SENSOR:
PASS OR FAIL
BUTTONS:
PASS OR FAIL
If any of the tests display “FAIL”, see the troubleshooting guide for recommended corrective procedures. The RAM
SIGNATURE test often displays “FAIL” on start-up because the RAM does not have any stored data. Simply press the
SELECT
to bypass the “FAIL” message. Once the processor is on line and operating, the RAM will collect data and
the test should pass on future restarts.
SYSTEM START DELAY
After the Diagnostic Self-Test is complete, the Timed Start Delay will be displayed and will start counting down from
the programmed delay. The factory setting is fi ve (5) seconds. Programmed in sub-menu 3-4 and ranges from 0 to 10
minutes in 5 second increments
BLOWER
1. The blower(s) will start upon completion of the Timed Start Delay and is programmed and wired to run continuously
during unit operation.
2. Cooling, reheat, humidifi cation and dehumidifi cation functions are inhibited for one (1) minute after the blower starts.
This allows the temperature and humidity sensors time to adjust.
COMPRESSOR COOLING
1. There is a fi ve (5) minute delay between start-to-start of the same primary stage compressor. The delay will be
increased to six (6) minutes for one (1) hour following the detection of a compressor short-cycle condition even if the
compressor short cycle alarm is disabled in Sub-Menu 4-8.
2. There is a two (2) minute delay between stop-to-start of the same primary stage compressor.
3. There is a one (1) minute delay between stop-to-start of the same secondary unloader stage compressor or stop-to-
start of a second secondary unloader stage compressor.
* Display only when module is installed.
