1. Introduction
LDSPH PLUS is a microprocessor based digital regulator for pH with temperature reading / compensation 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: 0 to 14 pH.All information are provided through a large LCD display.Using a revolutionary wheel
control the instrument can be easily programmed. LDSPH is housed in a IP65 plastic box.
INPUTS:
- Stand-by
- Flow
- pH level
- pH probe
- Temperature probe
- Water Meter
LDSPH-A PLUS Version stops probe’s reading when into STANDBY mode and activates the cleaning probe procedure
(if enabled and for set time into SELF CLEAN MENU) and restore time. At the end of the STANDBY a new cleaning
cycle and restore time re-start.
2. The wheel
Located in the upper right side of LDSPH 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, LDSPH shows the following main screen:
UNIT (1)
VALUES (2)
OUTPUTS STATUS (3)
Main screen zones:
(1) UNIT “pH” is the measuring unit for pH probe.
According to selected probe, this field may appear different.
(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
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”, pH (On/Off)
“pH pulse” and “pH pulse 2” outputs can be set to operate within: On/Off, Proportional (%) or disabled (OFF) modes.
“pH relay” and “pH relay 2” outputs can be set to operate within: On/Off, Proportional PWM, Fixed PWM or
disabled (OFF) modes.
8.2 “Set-Point”, pH (on/off)
This mode is valid for all pH related outputs. On/Off mode set the instrument to operate using two set values
that enable or disable the pH pump. To use this mode move cursor on “Working Mode”. Press the wheel and
select it.
ON/OFF mode while dosing ALKALI
Set pH value at 7.00 OFF and 6.90 ON. Set Pulse Speed per minute (strokes per minute) based on dosing device
capabilities.
Instrument will leave the pH pump active until reading value will increase up to 7.00pH.
At 7.00pH the pH pump will be disabled until reading value will decrease under 6.90pH.
This mode is valid for all pH related outputs. ON/OFF mode while dosing ACID
Set pH value at 7.00 OFF and 7.10 ON. Set Pulse Speed per minute (strokes per minute) based on dosing device
capabilities.
Instrument will leave the pH pump active until reading value will decrease up to 7.00pH
At 7.00pH the pH pump will be disabled until reading value will increase up to 7.10pH.

8.2 “Set-Point”, pH proportional & proportional water meter (pulse)
This mode is valid for “pH pulse” and “pH pulse 2” outputs only.
Proportional mode set the instrument to operate using a calculated percentage between two set values that
enable or disable the Chlorine pump. To use this mode move cursor on “Working Mode”. Press the wheel and
select it.
PROPORTIONAL mode between 7pH(0 P/m) and 8pH (180 P/m). p/m is : pulses per minute
In this mode the pH pump will be “ON” for values greater than 8pH with maximum set pulses per minute capacity
(e.g.: 180) and it’ll be “OFF” for values lower than 7pH. For values of 7.5pH pump will be “ON” with 90 pulses
per minute capacity. The calculation is based on 180 pulses per minute setting (see page 22). To end procedure
move cursor on “OK” and press wheel to proceed to “Save” request screen. Move wheel on “YES” to save or
“NO” to discard changes.
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 9 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
