E5@C Digital Temperature Controllers User’s Manual (H174)
*
If the Controller is equipped with HB/HS alarm detection, it is set by default to
ha
(Heater Alarm). If the
Program Pattern parameter is changed to a setting other than OFF, Auxiliary Output 1 Assignment parameter
is set as the program end output.
• The heating/cooling operation of the control outputs will switch when the Direct/Reverse
Operation parameter is set to direct operation.
• When DRS (Invert Direct/Reverse Operation) is set for an Event Input Assignment 1 to 6
parameter, control will start with the opposite of the setting of the Direct/Reverse Operation
parameter when the event input turns ON. When the event input turns OFF, control will return to
operation according to the setting of the Direct/Reverse Operation parameter. For details on event
inputs and control combined with the Direct/Reverse Operation parameter, refer to Control by
Inverting Direct/Reverse Operation on page 5-13.
• If heating/cooling control is selected, also set the Dead Band, Proportional Band (Cooling),
Integral Time (Cooling), Derivative Time (Cooling), and Heating/Cooling Tuning Method
parameters.
z
Dead Band
• For heating/cooling control, the dead band is set with the set point as its center. The dead band
width is the set value of the Dead Band parameter (Adjustment Level). Setting a negative value
produces an overlapping band.
• If an overlapping band is set, the bumpless function may not operate when switching between
manual operation and automatic operation.
• The default is 0.0 EU for Controllers with Temperature Inputs and 0.00% FS for Controllers with
Analog Inputs.
