LOCAL VISUAL POSITION INDICATOR
EMERGENCY MANUAL OVERRIDE FACILITY:
All J4M actuators are supplied with a local visual posion indicator (Fig.6).
The OPEN posion shows the indicator in BLACK and at the end of the stroke (max 14 turns) shows
the full indicator in RED.
The J4M has 2 operang modes, automac and manual, the required mode is selected by
using a lever on the lower half of the actuator housing (Fig 7).
Warning: Do not remove the selector lever securing screw, as this will allow its internal mechanism
to become loose and will cause irreparable damage to the actuator’s gearbox.
Removing this screw will invalidate the warranty.
When “AUTO” posion is selected:
The hand wheel rotates automacally, it is very important not to block it, otherwise the actuator
could suffer unrepairable damages.
The 2 posions are marked:
AUTO = Automac operaon
MAN = Manual operaon
