GENERAL TEST INFORMATION — The self-test routine
requires the user to login with Admin access.
The self-test routines will NOT operate if there is an active
alarm. If the user attempts to start a test with an alarm, the point
will automatically switch from On to Off.
During the testing, the BACview alarm lamp will be on and
the fans, compressors, and heating should halt operation, ex-
cept during the applicable tests.
The self-test routines will halt if there is an active alarm.
The self-test routines will lock the unit into test mode for 4
minutes after the last test has completed.
At test start-up and at each test step, the alarm output relay
will turn on for 2 seconds. The relay status is indicated by a red
LED adjacent to the output.
VARIABLE VOLUME FAN TEST SEQUENCE (VAV
UNITS ONLY) — The VAV fan test cannot be conducted
while running the compressor start/stop test.
1. As the alarm relay closes, the supply fan should start
and ramp up to 20% speed.
2. Thirty seconds after the test starts, the supply fan should
ramp up to 35% speed.
3. After 60 seconds the test point should be off and the fan
should stop.
CONSTANT VOLUME FAN TEST SEQUENCE (Non-
VAV Units Only) — The airflow type (base configuration
screen) should be set to constant. This test cannot be conducted
while running the compressor start/stop test. This is the same
test point used to test the VFD bypass.
Since constant volume units do not have remote VAV termi-
nals, there is no built-in delay to allow remote boxes to open
before starting the fan.
1. As the alarm relay closes, the supply fan should start at
full speed.
2. After 5 seconds the test point should be off and the fan
should stop.
VFD BYPASS TEST (VAV Units Only) — The airflow type
(base configuration screen) should be set to variable. This test
cannot be conducted while running the compressor start/stop
test test.
The VFD bypass control switch must be set to line (bypass)
mode.
The access panel secure (Access Panel SC) on the CNTL
CONFIG screen must be set to yes to allow this test to operate.
1. As the alarm relay closes, the TRMOP output engages
to signal the remote boxes to open.
2. Thirty econds after the test starts, the supply fan should
start at full speed.
3. After 60 seconds the test point should be off and the fan
should stop.
COMPRESSOR START/STOP TEST — This test operates
each compressor, individually, for 5 seconds. If a compressor
fault is detected for two continuous seconds, this test should
terminate.
