You may set the operating parameters of 4 different external inputs:
LEVEL 1 (5-6)
•
LEVEL 2 (7-8)
•
FLOW SENSOR (proximity) – (9-10)
•
EXTERNAL COMMAND (11-12)
•
Refer to Fig. 8 for the connection to the respective terminals
By DEFAULT, the proximity sensor and the external contact are set at NORMALLY OPEN. Therefore if the contacts open, the
device displays this on the screen and the pumps are blocked.
Attention: it is strongly recommended to use the device coupled to a flow sensor (proximity) which gives consent for
dosage only when the flow passes through the plant.
The device is supplied with the terminals of the PROXIMITY SENSOR and EXTERNAL SIGNAL jumpered, (see Fig. 8), so
that, with the default settings, the device can operate without connecting external sensors.
Eliminate these jumpers when the consents are used. Otherwise check whether the overdosage alarm triggers with a
time compatible with the application. By default, this alarm triggers with a control time of 10 minutes.
