1. Introduction
LDSCD is a microprocessor based digital regulator for conductivity with temperature reading and mA module (feed
forward). On/Off, impulsive proportional, proportional PWM or fixed PWM, Water Meter and PID are main working
modes.Also available FEED FORWARD setting for mA module. Pulses per minute can be set for outputs.Working ranges
are: Conductivity: from 0 to 10 mg/l. All information are provided through a large LCD display. Using a revolutionary
wheel control the instrument can be easily programmed. LDSCD is housed in a IP65 plastic box.
For LDSCD PLUS D version refers to page 31.
INPUTS:
- Stand-by
- Flow
- Conductivity level
- Conductivity probe
- Temperature probe
- Water Meter
2. The wheel
Located in the upper right side of LDSCD there is a wheel that must be used to control the instrument. Wheel can
be rotated in both directions to scroll over the menus and / or pressed to confirm highlighted selection / value.
NOTE: Once changes are made press “OK” to save and exit from submenu. Press “ESC” to exit without saving.

4. Main Screen
When into normal operating mode, LDSCD shows the following main screen:
UNIT (1)
VALUES (2)
OUTPUTS STATUS (3)
Main screen zones:
(1) UNIT Values read by the probe. “mS” - “uS” - “PPM/TDS”* are the measuring unit
for Conductivity probe. To change unit refer to “International” menu.
(2) VALUES These numbers are values read by the probes.
According to selected probe, this field may appear different.
(3) OUTPUTS STATUS These fields are related to current outputs status and instrument activity.
For more information rotate the wheel when into main screen. (see next page)
During critical situations a warning / alarm message may appear. To
in-depth explanation completely rotate clockwise the wheel to review main
instrument parameters and current outputs status.
*sold as option
*PPM / TDS unit is based on 1mS = 640 PPM of TDS (total dissolved solids)
Note: the word “PUMP” as shown into this manual refers to a “dosing device” connected to the instrument!

6. Password
To grant access into “Main Menu” press the wheel from main screen and enter the passcode.
If this is the first time here then the passcode is 0000 (factory preset). Press wheel 5 times to enter into “Main
Menu”. Otherwise press the wheel 1 time and enter the passcode. Numbers can be selected rotating the wheel.
To set a new passcode choose “PARAMETERS” from “Main Menu” , move on “New Pcode”, click on wheel and
enter a four numbers code. Click on “EXIT” and choose “YES” to save request. The new passcode is now ready.
Lost passcode ?
Please dont’ forget the passcode (if changed). In the unfortunate event, please call your local distributor for unlocking procedure. There is no way for you
to recover lost passcode.

8.1 “Set-Point”
“CD PULSE 1 ” and “CD PULSE 2” outputs can be set to operate within:
On/Off, Proportional (%) or disabled (OFF) modes.
“CD RELAY 1” and “CD RELAY 2” outputs can be set to operate within:
On/Off, Proportional PWM, Fixed PWM or disabled (OFF) modes.
8.2 “Set-Point”, Conductivity (on/off)
All Conductivity outputs can be set to operate into this mode.
This mode enables Conductivity pump to operate between two On/Off values. Move wheel over “Working
Mode” to select it.
ON/OFF mode
Set Conductivity value at 1,50mS ON and 2,00mS OFF. The difference between the two Conductivity values is called
HYSTERESIS.
Instrument will enable the Conductivity pump when reading value will decrease at 1,50mS
At 1,50mS the Conductivity pump will be enabled until reading value will increase at 2,00mS.
Pulse Speed: pulses per minute setting.
1,50 2,00
ON
OFF

8.2 “Set-Point”, CD proportional & proportional water meter (pulse)
This mode is valid for “CD pulse” and “CD pulse 2” outputs only.
Proportional mode set the instrument to operate using a calculated percentage between two set values that
enable or disable the Conductivity pump. To use this mode move cursor on “Working Mode”. Press the wheel
and select it.
PROPORTIONAL MODE between 2,00(0 P/m) and 1,50(180 P/m). [P/m: pulses per minute]
This mode operates Conductivity pump for a value lower that 1,50mS with maximum dosing capacity (180strokes) and
it will stop Conductivity pump for a reading value higher than 2,00mS.
Proportional Water Meter
Proportional mode can also be set into PROP+WM mode. This option allows to regulate proportional input based on
flow detected by water meter at set percentual values.
e.g.: reading at 0.90 will have an output of 90 P/m (50%). Adding the proportional flow from the water meter with
parameters set between 20 % (at 0mc/h) and 100% (at 8mc/h) results will be that (as example):
At 4 mc/h will have a working period of 54 P/m (60% of 90P/m)
60% is the middle value between 20% and 100% for reading of 4mc/h
