PF relay adjustments:
Depending on the characteristics of the motor and of the installation,
some simple adjustments must be made to the PF relay.

• With all the micro-switches to the left (OFF), the set current is
the basic current of the relay (4A for the PF 16-R and 16A for
the PF 47-R).
• When we place a micro-switch to the right (ON), we add its value

Trip class setting "Trip class"
The different trip classes allow to
adapt the overload protection to the
different applications of motors.
For submersible pumps, adjust to
class 10 (recommended value).
Place the first micro-switch to the
right (ON) and the second to the left
(OFF).

Underload setting "cos ϕ setting"
3
The adjustment of the underload trip level by cos ϕ is made trough
a potentiometer graduated form 0.15 to 1.0.
3.1 Quick adjustment:
a) If the pump is adequately dimensioned, the
recommended value for the adjustment of the
cos ϕ is 0.5. This applies in the majority of cases.
Adjust the potentiometer "cos ϕ setting" to 0,5
b) If the power of the motor is excessively
dimensioned and during its functioning,
unwanted trips should occur, the cosϕ adjusted
factor should be reduced to 0.4.
3.2 Step-by-step adjustment:
If the above mentioned cos ϕ values are unknown, the underload
trip setting can be made in the following way:
1. Set the underload trip delay to zero by moving the three
dipswitches to the left (trip delay).
2. Using the potentiometer (cos ϕ setting), set the cos ϕ value to
the minimum 0,15.
3. Start up the motor and run it with the minimum estimated load.
4. Slowly turn the cos ϕ potentiometer clockwise until the relay
trips and the cos ϕ LED lights up.
5. Turn the cos ϕ potentiometer anticlockwise until the cos ϕ is set
at approximately 30% less than the previous value (point 4).
6. Set the underload trip delay using the 3 corresponding dip
switches.

Recommended time 5 seconds.
Place the first micro-switch to the
right (ON) and the second and third
to the left (OFF).

Reset mode setting "Reset"
To choose this mode, place the
gliding micro-switch in "auto"
position, to the right.
After
trip, the reset will occur
after 4 minutes approximately,
uninterruptedly, until normal
conditions are recovered.
After
or
trip, the reset will occur after 4 minutes, only if
normal conditions have been recovered.

The adjustment of the reset time is
made through the potentiometer
graduated from 2 to 75 minutes. Fo-
llowing the trip by cos ϕ, the reset will
occur after the period of time adjusted.
It is possible to extend the reset to
525 minutes via the PR-RM module
