Severity Persistence
NonLatch The BAS was setup as "installed" at the MP and the Comm 3 LLID lost
communications with the BAS for 15 contiguous minutes after it had been
established. Refer to Section on Setpoint Arbitration to determine how
setpoints and operating modes may be effected by the comm loss. The
chiller follows the value of the Tracer Default Run Command which can
be previously written by Tracer and stored nonvolatilely by the MP (either
use local or shutdown).
Special NonLatch The BAS was setup as "installed" and the BAS did not communicate with
the MP within 15 minutes after power-up. Refer to Section on Setpoint
Arbitration to determine how setpoints and operating modes may be
effected. Note: The original requirement for this was 2 minutes, but was
implemented at 15 minutes for RTAC
Info Latch The real time clock had detected loss of its oscillator at some time in
the past. This diagnostic can be effectively cleared only by writing a new
value to the chiller's time clock using the TechView or DynaView's
"set chiller time" functions.
Info NonLatch The entering evaporator water temp fell below the leaving evaporator
water temp. by more than 2°F for 100 °F-sec. For RTAC this diagnostic
cannot reliably indicate loss of flow, but can warn of improper flow
direction through the evaporator, misbound temperature sensors, or
other system problems
Latch Continual loss of communication between the MP and the Immediate
Functional ID has occurred for a 30 second period.
