Page 7: Auxiliary Microswitches
AUXILIARY MICROSWITCHES On request, AB1 gear motor can be supplied with 2 auxiliary microswitches, which can be adjusted in any position. Microswitches are voltage-free. Contact rating is about 5 A/250 with Ohm load and about 1 A/250 with inductive load. For adjusting the cams of auxiliary microswitches, proceed as for cams of endswitches as indicated in paragraph 9.1 chapter 9 “SETTINGS”. -
Page 8: Adjustments
ADJUSTMENTS Endswitches As already reported in chapter 4 paragraph 4.3 the AB1 electric rotary gear motor is supplied by the factory with adjustment foreseen for a 90° rotation angle. If higher or lower than 90° rotation angles are requested, proceed as follows: 9.1.1 Disconnect the operating lever system of the gear motor shaft and remove the cover. - Page 9 9.1.9 Once all adjustments have been carried out return the key inside the AB1 gear motor and reinstall the cover by fastening the 4 screws. 9.1.10 Reinstall the control lever system of the AB1 gear motor and test functioning of the whole system. Potentiometer/s 9.2.1 The potentiometer shaft is frictioned and is accessible from the upper side inside the gear motor.
