OUTPUT S4 SETTINGS
9.8.1 DEFAULT SETTING
By default, relay S4 is dedicated to alarms on pH and temperature faults:
- The contact closes, if the measurement is less than pH 0.10
- The contact closes if the measurement is above pH 14.10.
- The contact closes if the sensor Pt 100 is faulty (damaged cable).
Otherwise, relay S4 can be dedicated to another function:
• Either in alarm (relay fault S1 or S2): See § ADJUST ALARM
• Or cleaning function: See § CLEANING PROBE
9.8.2 ADJUST ALARM
This function activates relay S4 when the switch-on time of relays S1 or S2 is too long (e.g. injection time too long).
Go to the menu ADJUST ALARM
• This ALARM function is not available if the CLEANING PROBE mode is activated; So, go to:
CLEANING PROBE MODE
Deactivate first the cleaning function in CLEANING PROBE menu before to access to ADJUST
ALARM menu..
• If the CLEANING PROBE mode is disabled, the ADJUST ALARM function is available:
WITH ALARM / WITHOUT ALARM
Select WITH ALARM to activate the relay S4, then confirm.
TIME S1 0005 Sec
Enter the holding time max. for relay S1, then confirm.
TIME S2 0020 Sec
Enter the holding time max. for relay S2, then confirm.
SAVE ?
To record the settings, press the icon SAVE.
9.8.3 CLEANING PROBE
This function actuates the S4 relay when automatic cleaning of the electrode is required.
In order not to disturb the regulation, measurements are frozen during the cleaning routine.
Go to the menu CLEANING PROBE.
• If alarms are set up in ADJUST ALARM, the cleaning mode menu is not available; So, go to:
ADJUST ALARM
To access to the CLEANING PROBE menu, switch alarms mode to WITHOUT ALARM in menu
ADJUST ALARM.
• If the ALARM mode is not activated, the CLEANING PROBE function is available.
CLEANING YES / NO
Select YES to set up the cleaning routine, then confirm.
PERIOD 2300 Sec
Enter the cycle time between two cleaning routines, then confirm.
TIME 0010 Sec
Enter the duration of cleaning routine, then confirm.
DELAY 0010 Sec
Enter the delay before the measurement is resumed.
SAVE ?
To record the settings, press the icon SAVE.

PID REGULATION
REGUL. PID allows seting of a PID regulation through analogue output (0...20 or 4...20 mA) between terminals 3 and 4.
This output is no more dedicated to the copy of temperature measurement.
Go to the menu REGUL. PID
REGULATION ON / OFF
Select ON to set up the function PID REGULATION, then confirm.
REGUL. AUTO / MANU
Select AUTO to access to parameters, then confirm.
SET VAL 07.00 pH
Enter the value of desired trigger point, then confirm.
GAIN : 4.800
Enter the required proportional gain value, then confirm.
Ti : 0050 Sec
Enter the value for integral timer, then confirm.
Td : 0012 Sec
Enter the required value for derivative timer, then confirm.
ACID INJECTION / BASE INJECTION
Select the right chemical, then confirm.
OUTPUT 4/20 mA or 0/20 mA
Select the required output signal range, then confirm.
SAVE ?
To record the settings, press the icon SAVE.
Note: To block the PID regulation, set a voltage of 24V DC (=20 mA)between terminals 5 (+) and 6 (0).
