Suction pressure load limiting/unloading

Suction pressure load limiting helps to protect the

evaporator from freezing. A system is permitted to

load normally as long as the Suction Pressure is above

the "Suction Pressure 2.6 psig". Between

"Suction Pressure 2.6 psig" and the "Suction

Pressure 1.7 psig", loading is inhibited, even

though increased loading is required.
Between the "Suction Pressure 1.7 psig" and

"Suction Pressure Cutout", forced unloading is per-

formed every 2 seconds according to

Table 19 on page

129

. This situation would occur if the suction pres-

sure cutout transient override control is in effect (See

Low Suction Pressure Cutout (Software) Fault on Page

127

). The suction pressure cutout is programmed un-

der the PROGRAM key. The default Suction Pressure

Cutout is set at 26.1 psig.
Suction pressure load limiting is active at startup, to

only prevent loading of the compressors. Suction pres-

sure limit unloading will not occur until the system run

time reaches 5 minutes of operation to allow the sys-

tem to stabilize.

Sensor failure cutout fault

The Sensor Failure Cutout prevents the system from

running when a critical sensor (transducer, level sen-

sor, or motor winding temp sensor) is not function-

ing properly and reading out of range. This safety is

checked at startup and will prevent the system from

running if one of the sensors has failed.
The sensor failure safety will also fault and shutdown

a system while in operation, if a safety threshold is ex-

ceeded or a sensor reads out of range (high or low).

Following is the Status display fault message.
