In the Continuous Run Mode, the unit will not be shut
down except in response to a shut down alarm. Refer
to Section 4.4 for more detailed information on Contin-
uous Run Operation.
The microprocessor may be configured with Start-Stop
operation tied to the set point ranges for frozen and
perishable loads. The Start/Stop-Continuous key is
locked out if "START-STOP LOCKED" displays in the
MessageCenter when the key is pressed and the unit
is in Start-Stop Operation or "CONTINUOUS
LOCKED" displays in the MessageCenter when the
key is pressed and the unit is in Continuous Run Op-
eration. Refer to Section 5.1.1 for Configuration infor-
mation.
If the unit fails to start after three start attempts,
alarm 31 - "FAILED TO START-AUTO MODE" will be
activated.
While running, if the unit shuts down, an internal coun-
ter keeps track of the shutdowns. Should the unit shut
down three consecutive times without running a mini-
mum of 15 minutes between shutdowns, alarm 30
"FAILED TO RUN MINIMUM TIME" will be activated.
The shutdown counter is cleared when the unit has run
for 15 minutes.
