Conversions to Engineering Units
Each 1 - 5 volt DC analog input will need to
be converted back into its appropriate unit of
measurement.
Conversions for each input are as follows:
ParameterConversion
Units
Temperature ( 0 – 99.9 ) = ((value) – 1) / 4 * 100
oC
Conductivity ( 0 – 9.99 ) = ((value) – 1) / 4 * 10
mS/cm
ORP ( 0 – 999 ) = ((value) – 1) / 4 * 1000
mV
pH ( 0 – 14.00 ) = ((value) – 1) / 4 * 14.00
pH
Corrosion Rates
as umPY1
( 0 – 1000 )= ((value) – 1) / 4 * 1000
umPY
as PIT1 ( 0 – 1000 )= ((value) – 1) / 4 * 1000
PIT
as umPY2 ( 0 – 1000 )= ((value) – 1) / 4 * 1000
umPY
as PIT2
( 0 – 1000 )= ((value) – 1) / 4 * 1000
PIT
Note: (value) = DC volts @ input = 4.00 Volts
Example: pH = ((4) – 1 ) / 4 * 14.00
= (3) / 4 * 14.00
= 0.75 * 14.00 = 10.50 pH
Testing
Once all connections have been made and all
conversions entered into the BMS, the BMS
interface must be verified.
For all analog inputs the reading on your BMS
display should be within 1% of the reading
displayed in the data display window on the
controller. If the BMS allows, these readings can
be calibrated to more accurately represent the
controllers’ reading.
If one or more readings is out of tolerance or
cannot be calibrated check your conversions and
record voltages at the input. If the voltage is OK
the problem is most likely in the conversion. If
the voltage is not OK, check the sense resistor
value and all cabling. LED’s L1 thru 8, on the 4-20
Interface Board, illuminate to highlight open circuit
or high resistance current loops.
For testing of Event Outputs, run the Test Outputs
routine whilst watching the BMS display. You
should see each relay output cycle ON for 5
seconds them OFF. Turn Flow ON and OFF and
watch for the flow indication at the BMS. Set an
Alarm in the controller (remove sensor, alter SET
point etc.) and look for an Alarm indication at the
BMS.
