G. ALARM CONTACT (OPTION)
The pre-alarm and main-alarm faults are indicated by snap contacts on the monitor which are transmitted
to terminal strips (see the wiring diagram in order to identify them).
The snap contacts are normally closed. They open when respective alarms are active.
H. OPERATION OF THE 4-20MA OUTPUT (OPTION)
The 4-20mA adjustment must be realised:
- at the first installation of the reactor,
- at each calibrating of the UV sensor.
The 4-20mA adjustment must be realised only after the UV sensor calibration.
(See Chapter MANUAL OF THE MONITOR BIO-UV MIII)
The 4-20 mA output is the image of the UV-C sensor output not the image of the UV-C
% display on the monitor screen.
CALIBRATION OF THE 4-20MA OUTPUT:
1
Before the second step, you must realise the UV-C sensor calibration.
2
Turn the small screw clockwise
until the red LED lighting.
3
The 4-20mA output is calibrated at 100% of UV sensor.
I. POWER REGULATION OPERATION
Equipment fitted with power regulation is designed specifically for your installation to ensure optimum
operation even at the end of the lamps' service life:
When the lamp is new and while UV transmission is sufficient (over 70%) it is automatically set at 70%
power. When the UV transmission falls below the required level, the power is increased to 100% so as to
increase the UV rays transmitted.
This control system is designed to increase lamp life and allow energy savings whilst guaranteeing
sufficient UV rays in the long term.
To switch the power regulation on or off, refer to the chapter "Manual of the monitor MIII".
NOTE: When the power regulation device goes into automatic mode, it is necessary to restart the reactor
for the change to be taken into account.
