Tecnoplastic Crab UL Instructions

NOTES: DO NOT TAMPER WITH THE FLOAT SWITCH. THE NON RESPECT OF THE
FOLLOWING POINTS WILL AUTOMATICALY CAUSE THE CANCELLATION OF THE
WARANTY OF THE PRODUCT
• Before any operation on the float remember to disconnect the power supply
from the main power.
• Check that the maximum motor power does not exceed the float's electrical
values.
• In case of cable damage by the final user or installer, the float must be
replaced.
• Do not make any joint on the cable of the float switch, as immersion of such
joints could cause short circuits or electrical shocks.
• Overcurrent and overload protection to be provided when used for motor
load:
• Overcurrent protection is provided by one of the following:
i. A listed molded-case circuit breaker marked for use with 16 AWG wire
ii. Listed fuses marked for use with 16 AWG wire
iii. Class CC, Class J, or Class CF, Class T fuses
• For use only in industrial machinery NFPA79 applications
• For use only with thermally protected sump pumps (Only for model
A-02D-SPST)
• Suitable for water application only

USE:

The electronic controller is designed to work in clear and rain water. Supported on
a flat surface, it remains anchored to the bottom. It can detect the presence of
water at 3mm ±1 from the floor. The electronic regulator has two delay times: start
and stop (shutdown) which can be adjusted by the final customer according to his
needs of use.

SET DELAY TIMES:

The first time you connect the plug to the electrical system, the electronic
controller will perform a 5 seconds startup test to check the functioning.
STARTING DELAY TIME: 5 seconds.
The pump turns on 5 seconds after the water has raised touching the two sensors
placed at the bottom of the electronic regulator.
Change the Starting/Delay Time (Fig.1)
1. Disconnect the plug from the electrical system
2. Put the magnetic key close to the arrow stamped on the side of the electronic
controller.
3. Connect the plug to turn on the pump.
4. Hold the magnetic key in position for how many seconds you wish to delay the
starting time (maximum 120 seconds).
5. Once you got the desired delay time, remove the magnetic key.
SHUTDOWN DELAY TIME: 30 seconds.
The pump turns off 30 seconds after the water has flowed down releasing the
sensors.

Change the Shutdown Delay Time (Fig.2)
1. Connect the plug to the electrical system.
2. Wait for the pump shutdown.
3. Put the magnetic key close to the arrow shown on the side of the electronic
regulator and the pump starts.
4. Hold the magnetic key in position for the seconds necessary to delay the
shutdown (maximum 120 seconds).
5. Once reached the desired time, remove the magnetic key.

TERMINAL CONNECTIONS:

The upstream circuit must protect the electric wires from the overcurrent.
WARNING: lack of protection shall null and void the warrany in the event the
float breaks.
