COMPONENT FAILURE RESPONSE NORMAL RANGE DIAGNOSTIC
Traq - RTVM Communications
Failure
In the event of the loss
communications with the
RTVM in a system previously
configured for Traq control a
static OA Minimum Position
value of 10% will be utilized at
all times.
N/A
A diagnostic will be set via BAS
communication and the 2-blink code will be
initiated on the RTRM to indicate a
problem.
Traq - RTEM Communications
Failure
In the event of the loss
communications with the
RTEM in a system previously
configured for Traq control the
RTEM will revert to the Local
Design OA Minimum Position
potentiometer on the RTEM as
a fail safe built into the RTEM.
The damper will remain at that
position until communications
is re-established to the RTEM
or the power is disconnected.
Traq control will be disabled
since it requires transmission
of the Traq OA Minimum
Position Request to the RTEM
via Modbus link.
N/A
The proper diagnostic will be set via BAS
communication and the 2-blink code will be
initiated on the RTRM to indicate a
problem.
