5.6 Using Two Target Setpoints
•
This function is available for
UT150/UT152/UT155 with the "/EX"
option.
•
SP is switched using the external
contact inputs. The external contact
input terminals for SP switching are
different according to the parameter
"DIS" setting.
Refer to "8.3 Wiring" on Page 8-7.
•
Set "0" or "2" for the setup parameter
"DIS" to switch SP.
•
Set the ramp rate to prevent the target setpoint (SP) from changing suddenly.
Refer to "5.5 Setting Target Setpoint Ramp Rate (Rate-of-Change)" for ramp rate
setting.

•
The retransmission output range is
factory-set to between the maximum and
minimum values of measured input range
(scale).
•
The retransmission output range is
changeable. The retransmission output
range is set using the parameters "RTL"
(minimum value of retransmission output)
and "RTH" (maximum value of
retransmission output).
