Term Explanation
Pulse cycle
It is a function that sets one cycle time of output ON/OFF in case of ON OFF pulse
type or SSR drive pulse type.
The smaller the set value the better the controllability, however as the ON/OFF count
increases the life span of relay etc. decreases. Set the highest possible value in the
range such that there is no error in controllability.
Control operation
'Reverse operation' is a control operation for SV (Setting value) in which the lower
the PV (measurement value) the bigger the MV (output value) and it is generally
used at the time of heating operation.
'Direct operation' is a control operation for SV (Setting value) in which the higher the
PV (measurement value) the bigger the MV (output value) and it is generally used at
the time of cooling operation.
Output dead band
(Two-position control
operation)
It is a dead band of output operation
of two-position control operation
(when P=0%).
The smaller the set value the better
the controllability, however as the
ON/OFF count increases the life span of
relay etc. decreases. Set the highest
possible value in the range such that
there is no error in controllability.
Alarm dead band
It is a function that, activates the alarm at the alarm setting value during alarm
activation and releases the alarm, when the dead band that is set in the alarm setting
value exceeds the dead band that is set in alarm setting value during alarm release.
