4–5 Remote Set Point
Selecting PV1 or PV2 for SPMD will enable the TEC-2500 to accept a remote set point
signal. If PV1 is selected for SPMD, the remote set point signal is sent to input 1, and
input 2 is used for the process signal input. If PV2 is selected for SPMD, the remote set
point signal is sent to input 2, and input 1 is used for the process signal. To achieve this,
set the following parameters in the setup menu.
Case 1: Use Input 2 to accept remote set point
FUNC=FULL
IN2, IN2U, DP2, IN2L, IN2H, are set according to remote signal.
PVMD=PV1
IN1, IN1U, DP1, are set according to the process signal
IN1L, IN1H if available, are set according to the process signal
SPMD=PV2
Case 2: Use Input 1 to accept remote set point
FUNC=FULL
IN1, IN1U, DP1, IN1L, IN1H, are set according to remote signal.
PVMD=PV2
IN2, IN2U, DP2, are set according to the process signal
IN2L, IN2H if available, are set according to the process signal
SPMD=PV1
Note 1:
If PV1 is chosen for both SPMD and PVMD, an error code will appear. If
PV2 is chosen for both SPMD and PVMD, an error code will appear. In either
case, the TEC-2500 will not control properly.
Note 2:
If PV1/PV2 is selected for SPMD, a signal loss will result in the controller reverting
to manual mode with 0% output.
Setup
FUNC=FULL
SPMD=PV2, PVMD=PV1
or
SPMD=PV1, PVMD=PV2
Error message
Once the timer output is energized, it will remain unchanged until power down or an event input
programmed for resetting the alarm is applied.
Note:
TIMR can't be chosen for A1FN and A2FN simultaneously, or an error code will
result.
Ramp and dwell
A ramp may be accompanied with a dwell timer to control the process. Here is an example.
Example with ramp and dwell
Select HRR for SPMD, PU for IN1U, 2-DP for DP1, and set RAMP=60.00. Select TIMR for A2FN
and set TIME=20.0. When power is applied, the process value starts at 0.00, SP1=30.00, and
SP2=40.00. The timer output is used to control event input.
