Actuator Type ARIS, 4, 4a, 5
Description
The actuator type ARIS-N is designed
as a controlling element for oil/gas or
dual-fuel burners with sliding or modula-
ting control concept. The actuator is
equipped with a short-circuit-proof syn-
chronous a.c. motor which drives a
shaft via a maintenance free spur-gear
unit with permanent grease lubrication.
The shaft end carries a coupling for
operating the controlling element for
fuel and combustion air. The actuator is
designed for two-wire control by control-
lers or switching units with change-over
contact (single-wire control is possible).
A feedback potentiometer is used as a
optional feature.
