Alarm Contents
Alarm setting explanation
Status Occur cause Controller operating status at alarm
Remote sensing
Sensing time :
5 sec / Input
contact : A contact
/ Auto return
It occurs when the controller is not
detected or detected according to the
input contact set value for the detection
time on the remote sensing input(DI2) at
the time of operation or stop. The controller is operated or stopped by the
remote contact only while the controller is
running, and the controller can not be started
from the monitor when the remote is detected
in the stop state.
Halon sensing
Sensing time :
0.5 sec / Input
contact : Selectable
/ Manual return
It occurs when the controller is not detected
or detected according to the input contact
set value for the detection time on the halon
sensing input(DI2) at the time of operation or
stop. All operation status is stopped when halon is
detected. Even if halon detection is canceled,
user must set the controller directly to ON to
operate normally.
Halon detection is not released, it remains stopped.
Blower check
Sensing time :
10 sec / Input
contact : A contact
/ Auto return
After COMP output(DO3,5) when occurs
alarm when not detected in the blowing
alarm(DI3) status input for 10 seconds.
When an alarm occurs, not only all the outputs
but also the blower outputs are turned OFF.
When the alarm returns, the alarm is canceled
and the controller operates normally.
Comp 1~2 check
Sensing time :
Selectable / Input
contact : B contact
/ Manual return
After COMP output(DO3,5) when occurs
when detected or not detected according
to the input contact set value in COMP
Alarm(DI4,5) status input during alarm
sensing time.
When an alarm occurs, only the corresponding
compressor output for which an alarm has
occurred is stopped, and the operation is
switched to the operation standby unit. And the
other operation of the controller operates
normally.
