The MX52 C ONTROL requires a small amount of maintenance. However, it is recommended that the test functions

Check the functions of the control as follows:
Use the TEST switch to check the correct operation of all the LEDs and the buzzer.
Use the “SIMULATION” menu to check the correct operation of the display panel, the triggering of alarms
(LED and relays), the auxiliary devices and the 4-20 mA current output.
Cause a fault to occur (such as a line fault by disconnecting a detector wire) to check the correct operation of
the fault indications.
6.1.2 On the Sensor/Transmitters
