15.3 To Select Analog Output or Proportional Control
To determine if the meter is to transmit an analog signal out proportional to your display or
proportional to the error (proportional control) (The error is defined as the difference between
reading and Setpoint 1 value).
If you have selected “S.3=P” in Setpoint 1 Configuration ( “S1.CF” - refer to Section 11), you
cannot program the meter for analog output proportional control. You may, however, use the
regular analog output. If you have selected
“S.3=0” in Setpoint 1 Configuration, then you may
select analog output or proportional control as follows.
1. Press the / DEV button. The meter shows one of the following:
* “O.3=A” (Analog output is retransmission of temperature) (Factory default)
* “O.3=P” (Analog output is proportional to error between display reading and
Setpoint 1)
2. Press the / MAX button to toggle between choices.
3a. If you select O.3=A , press the MENU button to store your choice. The meter momentarily
shows “STRD” , followed by “OT.S.O” (Output Scale and Offset- refer to Section 18).
3b. If you select O.3=P , press the / DEV button. The meter shows one of the following:
* “O.4=D” (Proportional analog output is DIRECT ACTING)
* “O.4=R” (Proportional analog output is REVERSE ACTING).
4. Press the / MAX button to toggle between choices.
5. Press the MENU button to store your choice. The meter momentarily shows “STRD” ,
followed by “P.BND” (Proportional Band).
Additionally, if you select O.2=V (Analog output to be voltage), press the / DEV button.
The meter shows one of the following:
*
“O.5=F” (Proportional 0-10 V analog output)
* “O.5=H” (Proportional 0-5 V analog output)
6. Press the / MAX button to toggle between choices.
7. Press the MENU button to store your choice(s). The meter momentarily shows “STRD” ,
followed by “P.BND” (Proportional Band).
