Factory Performance Test
The following tests are performed on all Aquarius
D.I. Water Heating Systems after
assembly and before shipping. The units are tested with D.I. water supplied to the unit
and discharged to drain.
1. A high potentiometer test procedure is performed on the heaters used in the
Aquarius D.I. Water Heating System. The test procedure includes a leak,
thermocouple, and resistance test. For detail, reference document number 1201.
2. Voltage, Flow, and Pressure readings on the controller are calibrated as follows:
a. The incoming voltage is measured on the input side of the contactor by a
voltmeter. If the measured voltage reading does not match the voltmeter
reading on the screen, the voltage value is adjusted accordingly by
adjusting the voltage calibration parameter which is located on the
System
Calibration
screen of the
System Set Up Menu
.
b. An external flow meter is plumbed in-line with the D.I. water heater. The
flow reading on the touch screen should match the reading indicated on
the external flow sensor. If an adjustment is required the flow meter value
is adjusted accordingly by adjusting the flow calibration parameter which is
located on the
System Calibration
screen of the
System Set Up Menu
.
c. An external pressure meter is plumbed in-line with the D.I. water heater.
The pressure reading on the touch screen should match the reading
indicated on the external sensor. If an adjustment is required the pressure
value is adjusted accordingly by adjusting the pressure calibration
parameter which is located on the
System Calibration
screen of the
System Set Up Menu
.
For more detailed information on the Aquarius
control system and operation
screens please refer to the PF2000 Controller manual.
3. The Aquarius
control system is monitored and controlled by a PLC
(Programmable Logic Controller) and related hardware of the Aquarius
and
checked for functionality.
a. The inputs and outputs of the Safety PLC are checked and verified.
b. All components and sensors are checked and tested.
c. Control system functionality are checked and tested.
4. The Aquarius
D.I. Water Heating Systems are tested to operate with the
“Process Temperature Set Point”
parameter set to the maximum temperature
possible according to the equation below. This test will insure that all heater
modules are operating and full heater power is available.
a. The proper flow rate is first calculated using the following formula:
