KEY LABEL DESCRIPTION
*
[0] F1 Used only for some options.
[.] F2 Sequences: A series of functional steps (macros) which can be created, edited,
run, or deleted by the user. The full text relating to Sequences begins on page
3-11.
[+] Run: Next, requires a sequence number [nn], or [=] to rerun the most recently run
sequence.
[+] Create/Delete: To create a new sequence, or delete an existing one.
[+] List/Edit: To either list or edit a specific sequence macro.
[=] F3 Used only for some options.
[1] CAL Allows the user to calibrate transducers and the A/D electronics from the front
panel. After entering the CAL mode the [+] and [–] keys will scroll as usual,
but to enable any of these functions will require entry of a recognized password.
[=] Sensor Offset: Provision for resetting the zero offset of selected transducer.
[+] Sensor Span: Provision for resetting span sensitivity of selected transducer.
[+] Cal A/D: Automatic internal calibration of A/D circuits.
[+] Cal Aux Sensor: Displays auxiliary transducer pressure. Apply pressure at SUPPLY
port to check calibration.
[+] Save Control Settings: Part of an optional feature available for large volume appli-
cations. With this feature the control algorithm uses an adaptive process to ‘learn’
the optimum control parameters based on the existing external volume, line restric-
tions, and control point value. The specifics of this feature are covered in a
supplemental manual (ref: T427).
Optional Function:
[+] Baro Cal: Uses the optional Barometric Reference Transducer (BRT) as a standard
to calibrate the active transducer.
[=] Password: 6 digit user definable authorization code, initially set to 123456.
See ‘Chg Password’ under LIMITS Functions.
[2] TEST Performs a built-in test on certain electrical and pneumatic functions from a
menu of choices.
[=] All: Tests all of the following except System Leak, Keypad and Manual Valves.
[+] Sensor: Tests the active sensor for valid RAM checksum; displays pressure and
temperature A/D counts until [CE] or [2nd] [any].
[+] Source Pressure: Estimates the pressure at the SUPPLY port up to 110% FS max.
