RISK OF ELECTRIC
SHOCK
DANGER
WARNING
The “Mains power on” LED comes on to indicate that the board is functioning properly.
The motor can be governed directly by the operator with man present (Manual) or by remote
signals (Automatic) by means of the “Automatic – Off – Manual” buttons; (when the
automatic button is pushed the related LED above the button lights and the control panel is
ready to receive remote signals from the sensors and floats).
- G.MIN input can have double function:
With “AUTORITENUTA” jumper ON: G.MIN is used as STOP LEVEL (The 2 pumps continue
to run, after G1 and G2 command, until the G.MIN float switch is no longer tilted);
Without “AUTORITENUTA” jumper : G.MIN is used as MINIMUM LEVEL FLOAT SWITCH and
all the pumps can only work when the minimal level is exceeded.
With “EXC ALLAR.” Jumper it is possible to exclude the “LEVEL ALARM” red light
and the OUTPUT ALARM RELAY when G. MIN float switch is switches off.
This function is used when “AUTORITENUTA” Jumper is ON.
- G1 input is used as EXCHANGER function (it can be any free voltage contact – float switch)
- G2 input is used as EMERGENCY function (the second pump starts after 4-5 second)
- G.A. input is used as LEVEL ALARM function (when switches-on the 12Vcc SIREN output is
ON with a MAXIMUM absorption 30 mA)
The green pilot lights “Motor ON” indicate the functioning of the motors.
If the Overload protections are tripped
, the motors stop and the red “MOTOR PROTECTION
ENABLED” and the red “LEVEL ALARM” LED lights on. Push RESET to reset the alarm;
Check for the cause of the malfunction before restoring the motor to operation.
If the motor has 2 wires for the thermal protection of the motor winding, connect them to the
“THERMAL T1” input terminal. If the protection cuts in, the motor is cut out when the contacts
open. If the motor does not have a built-in protection, then it is necessary to make a jumper
on THERMAL T1 input in order to enable the motor.
- The ammetric protection tripping current can be adjusted by means of the
“CORRENTE MOTORE” (MOTOR CURRENT) Trimmer, based on the rated absorption of
the motor; the adjustment can be made from a minimum of 2A to a maximum of 22A.
The cut-in delay time is fixed at 5 seconds and can be overridden during setting by
bridging the “ESCL.TIM.TA” Jumpers;
GENERAL NOTES :
During the calibration for Over-Load Protection, start the motor 2-3 times to check the
correct operating.
