EF315_r5.1(v12.22) – 03/2023 page 17
PARAMETER 21 EXT.CONS. INPUT CONFIGURATION (NO / NC)
This parameter allows to configure the operating mode of the EXT.CONS. input.
- P20=0 EF315 unit enabled with input open (NO)
- P20=1 EF315 unit enabled with input closed (NC)
PARAMETER 22 WORKING TEMPERATURE WITHOUT PT100
Normally the reference / working temperature is the measure 3 value (PT100 sensor).
If no temperature probe is connected, the controller uses the value set in this parameter as working
temperature and as reference for thermo-compensation.
PARAMETER 23 PASSWORD FOR STANDARD CONFIGURATION
To prevent any access to the configuration menu by unauthorized personnel, set a protection password
in this parameter. In this case, when trying to access the standard configuration mode, the unit will
request this password before proceeding. The unit is supplied with no password (P23=0).
Warning! If password is forgotten, the unit must be sent to the manufacturer for a complete
reconfiguration (not under warranty)!
PARAMETER 24 PASSWORD FOR ADVANCED CONFIGURATION
Same meaning and use of parameter P23, but referred to the advanced configuration.
PARAMETER 25 LANGUAGE
This parameter allows to set the interface language, choosing among the 4 available options:
PARAMETER 26 / 29 FLOW RATE PUMP 1 / PUMP 2 (litres/h)
EF315 is equipped with the litre-counter of injected product. The flow rate of dosing pumps (Pump 1 and
Pump 2) depends on model and system back pressure, and therefore is a value to be set at installation.
It is important that this value is as close as possible to the real one, to avoid big displaying and totalization
errors. The total of injected litres is always shown on the third line of the display.
PARAMETER 27 / 30 AUTONOMY PUMP 1 / PUMP 2 (litres) – MAINTENANCE REQUEST
In order to prevent undesired stops of the system and always keep its top performance, it is
recommended to schedule maintenance interventions. For dosing pumps, the maintenance frequency
depends on the amount of injected product.
This parameter allows to set a volume threshold (dosed litres) beyond which the EF315 unit will require
maintenance. This request can be a simple warning message or even generate an alarm, with
subsequent disabling of the pump, by properly setting the parameters P7 and P14. If this function is not
needed (for example, in case of P2 output used for triggering a salt chlorinator), set the related parameter
to zero.
PARAMETER 28 / 31 RESET LITRES PUMP 1 / PUMP 2 – ENTER PASSWORD FOR RESET
After performing the scheduled maintenance, enter in this parameter the password (default = 12) to zero
the litre-counter and remove the maintenance request message.
PARAMETER 32 LED POWER
This parameter allows to set the way the LED POWER indicates the instrument status.
If P32 = 0, the LED can blink in three different modes:
• Slow flashing regular operation of the controller
• Quick flashing indication of an alarm, fault or block condition
• Two flashes and one pause data editing or calibration in progress
If P32 = 1, the LED can blink in two different modes:
• Steady light regular operation, no alarm
• Quick flashing indication of an alarm, fault or block condition
