Instruction Setting
Visualization:
The instrument can control many different measures, for shown every measure is possible to select three
different screens with the key Up and Down. In the default screen are shown the Chlorine measure, the
Redox measure, the temperature measure and the pH measure. In the second screen are shown the
resettable totalizer and the date from the last reset, if the date is not set the display will write “install”. In the
third screen there are the Flow rate measure and the value of the permanent totalizer.
Functions:
• Calibration (Press Cal Key for 3 Seconds):
o Select the calibration routine for: Redox, pH, Chlorine or Flow rate by Up or Down key.
o Standard Routine calibration pH probe is 7 and 4 buffer solution and Redox 465 mV buffer
solution.
• Press Cal and Set Key (both) for 5 Seconds and run Program Setup:

pulses/liter; adjust value between I=0÷999 L=0÷999. If the sensor is
calibrated in this menu (K Factor and Water Meter), the string “Cal” appear
for a couple of seconds in place of the actual number, indicating that the
instrument will use the parameter recalculated based on the calibration.

SW) Leave the SWITCH on the “1” position. This switch is
intended to improve the communication and to reduce noise in
installations with very long cables (>50m). If you have long cables
and are facing communication problems, you can try to solve the
problem, sliding the IMPEDANCE MATCHING SWITCH to the
“ON” position only for the first and the last device present on the
bus. (i.e. the two devices farther away from each other). Leave
instead the IMPEDANCE MATCHING SWITCH on the “1”
position for all the other intermediate devices along the bus.

When the system is set ON (on= Stop) change the status, as follow:
• All relays are disabled
• All outputs are disabled (not freq. signal, outmA frozen at 4 hold value)
• All alarms are disabled
• All manual pump activations are disabled
• Keyboard button are enabled
• Reset parameters function is disabled
• Interrogating the device via Modbus will not show the alarms
• Once the “remote stand by” is deactivated, the device restarts from the status before remote Stop
event.
• Input level and Flow input are detected but if we have an alarm it doesn’t generates any alarm on
Modbus or on Alarm relay.
Some basic recommendations for connecting the RS485 line:
All devices on the line must be connected “one after the other” and not in a “star”
(see image on the right).
