F28 - Setpoint for semi-artesian wells or water tanks:
It is the reference value for controlling the water level. Level (in mwc) where the pump is switched off.
F29 -Hysteresis for semi-artesian wells or water tanks:
The difference in level between the pump switched ON and OFF.
F30 - Transducer P1 installation level for control of wells/tanks:
It is the reference value representing the distance (in meters) from the surface to the depth/height at which
the P1 transducer is installed.
The value displayed when the display mode is equal to
[MtrS]
- Depth/height of water level relative to
the surface (in meters) will be the difference between this level and the water level read by the P1
transducer.
F31 - Critical water level for control of wells/tanks:
Level (in mwc) at which the low water level alarm is generated
[Ah2o]
.
If set as the control for the semi-artesian well, the pump is switched off if this level is reached in order to
prevent the pump from running dry.
This alarm is only generated after the time specified in the “
[F57]
-
” setting.
Alarm validation time
F32 - Wells/tanks control time on (cyclical timer):
F33 - Wells/tanks control time off (cyclical timer):
These functions allow the length of time that instrument will control the pump operation to be regulated
when the “
[F04]
- 1st stage operating mode (OUT1)
” setting is set to control semi-artesian wells and
water tanks (pressure switch with cyclical timer).
During the time it's turned on, the pump is controlled by the parameters for the water level setpoint and
hysteresis. During the time it's turned off, the pump will continuously stay turned off and the level alarm will
be ignored. This time is needed for the level of the well water to regenerate.
By setting the time to 0 (off), the control will remain constantly active.
Reversing the cyclical timer status can be performed manually through digital input 2 by setting the
“
[f59]
-
” to reverse the cyclical timer.
Digital input 2 operating mode
F34 - Filter Control - Difference (P1-P2) for starting the pump:
Allows the pressure difference between the filter inlet transducer (P1) and the filter outlet transducer (P2)
to be set in order to release the passage of liquid (pump or valve). When the pressure difference (P1-P2)
is less than or equal to the value set in this function, the passage of liquid to the filter is released.
F35 - Filter Control - Difference (P1-P2) for shutting down the pump:
Allows the pressure difference between the filter inlet transducer (P1) and the filter outlet transducer (P2)
to be set in order to close the passage of liquid (pump or valve). When the pressure difference (P1- P2) is
higher than or equal to the value set in this function, the passage of liquid to the filter is shut.
F36 -Enable alarm for changing the filter:
Allows the alarm for changing the filter to be enabled.

F38 - Pressure Setpoint OUT2:
This is the reference value for pressure control.
F39 -Pressure control differential (Hysteresis) OUT2:
It is the pressure difference (hysteresis) between switching control output ON and OFF.
F40 - Minimum pressure setpoint allowed for the end user OUT2:
Avoids regulation of excessively low setpoint pressures by mistake.

[f57]
F54 - Time for setpoints validation (OUT2):
Upon reaching the setpoint the pressure or temperature must remain in this condition until this time has
elapsed and then switch off the control output (it avoids overshooting in the pump/compressor
activation)..
This function can be disabled by adjusting it to the minimum value 0
[no,,]
.
F55 -Minimum output off time (delay between activations) (OUT2):
It is the minimum time the output will remain off, i.e. the length of time between the last start up and the
next stop. The main purposes of this function are: minimize interferences in the mains of the facility
caused by the simultaneous activation of loads and avoid unnecessary activation of loads when there are
fast variations of pressure in the system.
This function can be disabled by adjusting it to the minimum value 0
[no,,]
.
F56 - Maximum output operating time OUT2 for maintenance (hourmeter):
Whenever the output is activated, the apparatus will count its operating time. When the counted time is
equal or longer than the one set in this function, the display will show the message
[Man2]
, signaling
that the compressor/pump must be serviced.
F57 - Alarm Validation Time (OUT1 and OUT2):
This is the time that a (pressure or temperature) alarm will remain disabled even in alarm conditions.
This inhibition time starts to be counted after the power on delay expires.
A low pressure (
[Plo1]
or
[Plo2]
) and high pressure (
[Phi1]
or
[Phi2]
) event needs to remain
in this condition for the time set in this function so that the instrument can generate low pressure (
[AP1L]
or
[AP2L]
) and high pressure (
[AP1h]
or
[Ap2h]
) alarms.

, are also validated only in the time set in this function.
The external alarms for the digital inputs (
[din1]
and

If an alarm is inhibited by the user (by pressing the

key for two seconds), this time is reset.
This function can be disabled by adjusting it to the minimum value 0

F60 -Rotation time between OUT1 and OUT2:
If the “
[f37]
-
’’ function is set to rotate, the OUT2 output will operate
2nd stage (OUT2) operating mode
as a backup for the OUT1 output, thus activation of the outputs will alternate over time causing each pump
to work for a certain time and accumulate similar usage times.
After the time set in this function is exceeded, the control output will be alternated in the
next cycle.
Note:
If the “
[f37]
- 2nd stage (OUT2) operating mode” function is set to rotate, the control parameters
(pressure, temperature and alarms) related to the 2nd stage will be ignored, because OUT2 control will be
related to the 1st stage parameters.
