Diagnostics
Diagnostic Menu parameters (on the Factory Page)
provide information about the controller unit that is
useful in troubleshooting. For example, the Out1A
parameter will identify what type of output has been
selected for Output 1A.
Select the parameter by pressing the Right Key . . The
information will appear on the Lower Display.
Some of the parameters in the Diagnostic Menu provide
information for factory use only.
To reset all parameters to their original factory values,
use the Full Defaults parameter under the Test Menu.
Test
This menu allows you to test outputs, test the displays
(upper, lower and status lights), and cause the controller
to revert to the defaults set at the factory. Reverting to
factory defaults will erase all preset software and the
controller will return to U.S. PID units (Reset and Rate)
and the Fahrenheit temperature scale.
Calibration
The Calibration Menu on the Factory Page allows
calibration of inputs and outputs. Calibration procedures
should be done only by qualified technical personnel with
access to the equipment listed in each section.
Before beginning calibration procedures, warm up the
controller for at least 20 minutes.
Restore Factory Values
Each controller is calibrated before leaving the
factory. If at any time you want to restore the factory
input calibration values, use the last parameters in the
menu: Restore Input x (1 to 3) Calibration. Press
.
.. No
special equipment is necessary.
Thermocouple Input Procedure
Equipment
• Type J reference compensator with reference
junction at 32°F/0°C, or type J thermocouple
calibrator to 32°F/0°C.
• Precision millivolt source, 0 to 50mV minimum
range, 0.002mV resolution.
Input x (1 to 3) Setup and Calibration
Inputs 2 and 3 appear only if the controller is the
enhanced version (F4P _ - _ _ AB - _ _ _ _).
1. Connect the correct power supply to terminals 1, 2
and 3 (see the Wiring Chapter and the Appendix).
2. Connect the millivolt source to input 1 terminals 62
(-) and 61 (+), input 2 terminals 58 (-) and 57 (+), or
input 3 terminals 56 (-) and 55 (+), with copper wire.
3. Enter 50.000mV from the millivolt source. Allow at
least 10 seconds to stabilize. Press the Right Key .
once at the Calibrate Input x (1 to 3) prompt
(Factory Page). At the 50.00mV prompt press
. once
and to store 50.00mV press the Up Key > once.
4. Enter 0.000mV from the millivolt source. Allow at
least 10 seconds to stabilize. At the 0.00mV prompt
press
. once and to store 0.00mV press > once.
5. Disconnect the millivolt source and connect the
reference compensator or thermocouple calibrator to
input 1 terminals 62 (-) and 61 (+), input 2 terminals
58 (-) and 57 (+), or input 3 terminals 56 (-) and 55
(+). With type J thermocouple wire, if using a
compensator, turn it on and short the input wires.
When using a type J calibrator, set it to simulate
32°F/0°C. Allow 10 seconds for the controller to
stabilize. Press
. once at the Calibrate Input x (1 or
2) prompt (Factory Page). At the 32°F Type J prompt
press
.
once and to store type J thermocouple
calibration press > once.
6. Rewire for operation and verify calibration.
