*RET.
When Auto return is enabled, the converter reverts to the measuring mode from
anywhere in the configuration menus, when no button is pressed during the set
time interval of 10 minutes.
Code 51
*MODE
The adjustment of the contact setpoints, the manual operation of the wash
system and a manual impedance check (on demand) can be setup for operation
in the maintenance mode. (Through the closed front cover).
Code 52
*PASS
Passcodes can be set on any or all of the access levels, to restrict access to the
instrument configuration.
Code 53
*Err.4.1
Error message configuration. Two different types of failure mode can be set.
Hard fail gives a steady FAIL flag in the display, and a continuous contact closure.
All the other contacts (controls) are inhibited (except HOLD contacts), and a Fail
signal is transmitted on the outputs when enabled in code 32.
Soft fail gives a flashing FAIL flag in the display, and the relay contacts are pulsed.
The other contacts (controls) are still functional, and the controller continues to
work normally. The call for maintenance is a good example of where a SOFT fail
is useful. A warning that the regular maintenance is due, should not be used to
shut down the whole measurement.
*SOFT If soft set to 1, Soft fail only gives a flashing FAIL flag in the display and no
pulsing contact
Code 54
Not used
Code 55
*CALL.M
Call for maintenance is a contact trigger to signal that the system has been in
service for longer than the set time without calibration. The user can set up to
250 days as a routine service interval.
Code 56
*DISP
The display resolution can be set to either 0.01pH or 0.1pH. Not applicable to
the ORP (mV) display.
