7.1 DESCRIPTION OF ADDITIONAL FEATURES
FLOW ALARM WITH FLOW SENSOR (OPTIONAL)
Should the pump fail to pulse for any reason, an alarm buzzer sounds to warn the user. The pump then stops by
itself and a warning red(#1 fig.12) LED comes on, signaling that it needs the user's attention. Moreover a yellow
led(#5 fig.12) comes on. The tolerance limit for the activation of this alarm to be activated can be set by the
user (number of the missed pulses before the alarm comes on).
Reference pulses: periodic break between a control and the following one.
Max count diff.: maximum pulses to which does not correspond liquid injection from the pump.
Example:
a) Reference value set by user = 100 pulses.
b) Maximum allowed variance = 12 pulses.
c) Actual pulses detected by the pump = X pulses.
If 100 - X > or = 12, then the pump will produce an audible alarm (buzzer).
REMOTE CONTROL OR LEVEL
This function allows the user to activate or de-activate the pump from a maximum distance of 100 meters away,
using a contact switch.
Note: if external flow sensor (optional) is not installed "Reference Injections" and "Max. Injection Difference" must
