6 .25 Common alarm relay set-up:
The common alarm relay, (relay 3, Fig .25) can be configured via the Advanced setting
menu to activate when one of the following alarms are displayed on the screen:
Hi pressure
Pressure above the Hi pressure alarm (1)
Lo pressure
Pressure below the Lo pressure alarm (4)
Low water level
Low water level is seen by the sensor in the tank .
Pump fail
A system pressure increase is not acheived in a 5 minute period .
A pump has run for longer than the set Pump run time value, 10 to 60
Pump run time high
minutes without stopping .
Pump activity high
A pump has started more than the Start Activity high value in 24 hours .
Sensor fail
The sensor input is above or below the normal input range .
This will allow remote monitoring of an alarm to help fault find or monitor the
system condition . The Common alarm relay can also be configured via the Advanced
setting menu to be open circuit (NO) or closed circuit (NC) when the alarm is active
allowing the output signal to be changed .
6 .26 Hydraulic commissioning:
Ensure both inlet and outlet hydraulic connections are made using the
z
supplied rubber sealing washer and are watertight .
Turn on water supply to APU – Check for leakage and operation of fill
z
valve .
Allow the tank to fill and water level to stabilise . Adjust the float of the
z
fill valve to set the water level if needed .
Bleed pumps by undoing the slot
z
head bleed screw on the pump body
by ½ a turn until water can be seen to
flow out . Nip up, do not over
tighten .
Close isolation valve on the outlet of
z
the APU .
Turn the electrical supply ON to the
z
APU . The ADEY start up logo will be
displayed and then the Home screen will
be displayed .
The APU will run briefly and then turn off after a pre-set run on time .
z
Due to the small size of the isolated system the APU will signal a Hi
pressure error and the red error light will illuminate on the front of the
APU, this is normal .
Open the isolation valve on the outlet of the APU and the APU will
z
run and start to fill the system .
