For Fleck Valves:
NOTE:
This diagram can be adapted for any number of devices so long as when any one opens, the
connection to the MediQA is opened.
WARNING:
Failure to remove the jumper between X24-1 will prevent pretreatment lockout.
This will allow the MediQA to operate at all times, regardless of the status of the
pretreatment.
5.4.2
Heatsan Water Loss Lockout
Heatsan water loss lockout will prevent the MediQA from operating while the water loss alarm is
active on the Heatsan. This feature stops the flow of water to allow a leak to be dealt with. Once the
leak is fixed, the alarm can be cleared on the Heatsan and confirmed on the MediQA. This feature is
enabled by the MINT cable connection between the Heatsan and the MediQA.
5.4.3
Alarm Panel Connections
The
MediQA
utilizes fail safe connections for the Alarm Panel. The alarm output is normally closed,
so that when there is an alarm, this opens. AmeriWater supplies an alarm panel that can be set to
either normally open or normally closed contacts. As shipped, the alarm panel will look for a closure
to indicate an alarm condition. See the manual for the AmeriWater alarm panel for detailed
instructions on changing the input type.
To connect the
MediQA
to the alarm panel, run a signal wire from Y15-55 to the input on the alarm
panel for RO alarm. When the MediQA goes into alarm, the connection will open.
5.4.4
Installation Kit Details
Each
MediQA
will be shipped with an installation kit.
The temperature probe will need to be installed into the top port of the cross. The compression
fitting will need to be loosened (do not remove) to allow the probe to slide into place. When installed
properly, the ridge on the probe will be flush with the top of the fitting. Secure this connection to be
tight by hand, then use a wrench to tighten 1-2 turns.
