REMINDER
The handling operations and adjustments described in this chapter must be performed by
authorized personnel only, as they are liable to affect detection safety.
Once the measuring unit has been switched on, it can be programmed (1), its measuring channels
can be programmed (1) according to the detectors used and calibrations can be made on the unit and
detectors.
(1) These programming operations can be carried out directly on the MX52 unit in accordance with
the following procedures or using a computer equipped with the “com 52” software.
5.1.
Programming the unit
To program the MX52 measuring unit, and according to the required specifications, the “Unit
programming” menu must be used (see Section IV-2 on Menus) by means of the keypad and the
“Programming” key. Then, the instructions in the menu should simply be followed.
CAUTION
If the unit remains in programming mode for more than 30 minutes, it automatically switches to
fault mode.
5.2.
Programming the measuring channels
5.2.1.
Programming
To program each measuring channel according to the type of detector used and the required
specifications, the “Channel programming” menu must be used (see Section IV-2 on Menus) by
means of the keypad and the “Programming” key. Then, the menu instructions should simply be
followed.
REMARK
When a channel is switched on, all its relays are in “off” mode and its current output is 1 mA. Then,
one minute later, the channel comes into effective operation (relays ready and output of 4-20 mA).
CAUTION
If a channel remains in programming mode for more than 30 minutes, it is automatically switched
to fault mode.
