b. The calculated flow rate is introduced to the D.I. water heater and the unit
is turned on. The D.I. water heater is allowed to reach the process
temperature set point.
c. At 95°C, the unit may trigger the
High Temperature Alarm
. The
High
Temperature Alarm
indicates that adjustments are possibly required.
Make adjustments as indicated on the TROUBLE-SHOOTING GUIDE.
5. The Aquarius
D.I. Water Heating Systems are tested at
“Process
Temperature Set Point”
parameter set below the maximum temperature
possible and 1 GPM D.I. water flow. This will test the performance of the
controller.
a. The unit is allowed to operate with the controller
“Process Temperature
Set Point”
set to a value below the maximum temperature possible and
flow set to 1 GPM.
b. If the temperature is not stable, confirm that the controller’s parameters
are set to factory settings shown in the user’s manual. If further controller
tuning is required, see the TROUBLESHOOTING GUIDE.
6. The Aquarius
D.I. Water Heating Systems are tested for the correct operation
of the following safety interlocks or alarms:
a.
Components
: The components of the Aquarius
is thoroughly checked
for functionality, which includes the Safety Relay(CON2), Door Interlock,
EMO (Emergency Off), SCR (Silicon Controlled Rectifier), Safety PLC,
High Limit T/C Monitoring, Liquid Level, Thermal Cut-Off Sensor, Leak
Sensors (Optional), GFCI, and Current Transformer.
b.
Flow Sensor:
The system flow rate is indicated by the FLOW RATE value
readout on the
System Status
screen. Modify the current
“Low Flow
Alarm Set Point”
located on the
System Set Up
►
Alarm Set Points
screen. Set the
Low Flow Alarm Set Point”
value to just above the
FLOW RATE
reading on the
System Status
screen. The
Low Flow
Alarm
will trigger and the controller will disable the heaters and send the
unit into
STANDBY
mode. Return the
Low Flow Alarm Set Point”
to
the original setting.
c.
Pressure Sensor:
The system pressure is indicated by the PRESSURE
value readout on the
System Status
screen. Modify the current
“High
Pressure Alarm Set Point”
located on the
System Set Up
►
Alarm
Set Points
screen. Set the
“High Pressure Alarm Set Point”
value to
just below the
PRESSURE
reading on the
System Status
screen. The
High Pressure Alarm
will trigger and the controller should disable the
heaters and send the unit into
STANDB
Y mode. Return the
“High
Pressure Alarm Set Point”
to the original setting.
