To set the value:
1. Momentarily press and release either the setpoint increase or
decrease button (12). The green LED in both buttons lights,
indicating that the setpoint value may be changed.
The controller must be in the proper mode or the
local setpoint value will not take effect. Ensure that
the remote button LED is not lit and the green
setpoint increase/decrease button LED’s are lit
before attempting to alter the setpoint. During local
setpoint entry the digital display shows the local
setpoint value. The SP light to the left of the
display illuminates.
2. Set the new setpoint value using the increase/decrease buttons
(12).
3. The controller displays the new setpoint value in the digital
display for about seven seconds after release of the button, then
reverts to the configured display value.
If setpoint limits are configured in the controller, the controller does
not accept values outside such limits, The value shown on the digital
display will remain constant once a configured limit has been
reached. The SP bargraph also shows a full scale reading, O-100%
of the configured setpoint range.
Remote Setpoint/Extra Internal
SetpointXomputer Setpoint
The R button enables the remote setpoint value (RSP), extra internal
setpoint value (ESP), or the computer-generated setpoint value
(CSP). The green LED in this button lights to indicate Remote control.
The RSP value may be a setpoint value from another device, an ESP
value stored in the controller, or a CSP sent via the RS-485
communications link.
With the controller in the remote mode, display the actual RSP value
on the digital display by momentarily pressing either the setpoint
increase or decrease button. The R button LED remains lit as a
reminder that the displayed setpoint value cannot be altered manually.
