N N o o t t e e : : The above potentiometer voltage readings can
be verified via the provided test points located
next to each potentiometer. Use a DC voltmeter
to the Vdc reading between those points and
common.
Units Configured with the Outside Air
Measurement (Traq) Option
To make a minor correction to the Traq airflow (CFM)
reading that is calculated internally by the ReliaTel
system, an adjustment pot is available on the RTVM.
This pot can be used to correct for static "local" factors
such as altitude. Variable factors such as drift,
temperature, humidity, and other changing
atmospheric conditions are corrected as part of the
conversion calculation.
The adjustment will typically be made in Service Test
mode in a step where the OA damper is being
commanded to the Traq OA Minimum Position Request
with all required Traq control inputs valid (i.e. sensors,
setpoints, RTVM board). The OA flow adjustment
setpoint potentiometer (R136) on the RTVM will be
used to adjust the value up to a factor of +/- 20% (0.80
to 1.20) Full counter-clockwise will be – 20% and full
clockwise will be + 20%. The potentiometer will be set
to the middle position (between full CCW and full CW)
in a "Deadband" area representing no adjustment 0%
(factor of 1.00) by default. The adjustment will be
