Position Proportional Output Calibration - Honeywell DR4500A Product Manual

8.3 Position Proportional Output Calibration

Position proportional control
When the DR4500A Recorder has a position proportional control output, calibrate the recorder so that the
increase and decrease relays operate properly with respect to the position of the external feedback
slidewire.
Equipment needed
None
Connections
Leave all field wiring connected to the plugs in connectors J2 and J5 on the appropriate control output
printed circuit board.
Apply power and allow the recorder to warm up 15 minutes before you calibrate.
Auto mode vs manual mode
There are two ways in which to calibrate Position Proportional control:
AUTO mode or MANUAL mode.
Rules for auto mode vs manual mode
The auto-mode selection must be done at least once before the manual mode will operate properly. Failure
to use the auto-mode procedure will prevent the recorder from going into automatic control mode.
Displayed values
During the auto-mode calibration procedure, the values being displayed are used only to indicate if the
motor is still traveling.
To view the actual calibration value, use the manual mode after the auto-mode is completed. These values
can be changed for purposes of tweaking the calibration.
Procedure
The procedure for calibrating the position proportional output control output is listed in Table 8-3.
Make sure "LOCKOUT" in the Set Up group is set to "NONE." See Section 3 – Configuration. Also,

"CONTROL 1/2" must be enabled in the Control Set Up group.
Make sure "CONT ALG" = "PID A" and "OUT ALG" = "POSITN" in the Control Set Up group.
