5. ORP CONFIGURATION AND CALIBRATION
To access the 2 ORP Config., press
MENU
key, then scroll with the help of the
arrows.
To enter ORP Activation press OK, choose Activated or Deactivated and press OK.
ORP control cable output
The control cable provides a voltage
-
free contact between its two wires. Depending
on the configuration of the setpoints this contact can generate a signal with a
variable work cycle (PWM) proportional to the measurement, or an ON/OFF signal.
To use this cable to control a Chlorinator, configure the output in ON/OFF mode.
Connect the cable to the external control input of the Chlorinator or connect it to
operate with a relay or other device.
If you use the cable to switch a voltage, do not exceed the following values:
Maximum admissible voltage 230 VAC
Maximum admissible current 1 A
If percentage, when calculated, is different of 0% or 100%, contact will open and
close according to a variable work cycle (PWM) in cycles of 100 seconds. For
example, if the calculated dosaje is 40%, contact will remain closed (ON) during
first 40 seconds and open (OFF) for the rest 60 seconds.
Current status of this contact is shown permanently on display. When turning on the
device, it will wait for the ORP value to stabilize so, altough dosage is at 100%, ORP
output will remain OFF for a period of time. Also, the device has an hysteresis to
avoid fast changes and rebounds.
