AB1…SE instructions 2 of 12
Form 140516
1 GENERAL
FEATURES
Electronic rotary gear motors of series AB1...SE have been newly conceived and specially
designed to be installed on residential and industrial combustion systems.
They are particularly suitable for control and regulation of modulating disc valves, butterfly
valves, dampers and other fluid regulation systems requiring control of position angle
within 90°. Electronic rotary gear motors are unipolar and bidirectional with high static and
maintaing torque. Analogic input signal according to current [4 ÷ 20 mA] or voltage change
[0 ÷ 10 Vdc].

ARNING
Installation, wiring, adjustment and maintenance of gear motors must be carried out
exclusively by skilled and authorized service technicians. Non-proper installation,
adjustment, modifications, use and maintenance may cause injuries to the staff or material
damages. It is therefore necessary to respect strictly the following instructions and local
prescriptions for the installation of electronic devices.
