-
OFF = controller off
Use control Off to operate controller as a monitor only or to prevent relays
from switching.
-
L.CT = limit value control (on/off control).
Use limit control with pumps or values for fast response
-
P/PI = proportional/integral control
Use proportional control to operate your pumps smoothly or for precise
control of proportioning valves. Use PI controller to eliminate steady state
error.
Note: please refer to Appendix 4
for detailed information on controller
settings.
Press the ENT key
to confirm your selection.
If the controller is set to limit value control (L.CT):

Selecting the relay status under Non-Alarm condition: press the
▲
or
▼
key
to choose the desired relay status (de-energized = “DEEN” or
energized = “EN”).
Press the ENT key
to confirm your selection.
-
If the controller is set to proportional control (P/PI):
4.
Selecting the proportional controller type: press the
▲
or
▼
key
to
select the suitable controller type (“PLC” = pulse length control, “PFC” =
pulse frequency control).
Press the ENT key
to confirm your selection.
If the proportional controller type is set to
pulse length control
(PLC):
5.
Selecting the relay status under Non-Alarm condition: press the
▲
or
▼
key
to choose the desired relay status (de-energized = “DEEN” or
energized = “EN”).
Press the ENT key
to confirm your selection.
6.
Setting the proportional range. Press the
▲
or
▼
key
to set the
proportional range (setting range: 10 to 500%).
Press the ENT key
to
confirm your setting.
7.
Setting the pulse length. Press the
▲
or
▼
key
to set the pulse length
(setting range: 0.5 to 20 seconds).
Press the ENT key
to confirm your
setting.
8.
Setting the integral action time. Press the
▲
or
▼
key
to set the
integral action time (setting range: 0.0 to 999.9 minutes).
Press the ENT
key
to confirm your setting.
Note:
If the integral action time is set to ‘0.0’, then the unit functions as a
‘P’ Controller.
If the proportional controller type is set
to pulse frequency control
(PFC):
9.
Selecting the relay status under Non-Alarm condition: press the
▲
or
▼
key
to choose the desired relay status (de-energized = “DEEN” or
energized = “EN
”). Press the ENT key
to confirm your selection.
