LOCAL VISUAL POSITION INDICATOR
EMERGENCY MANUAL OVERRIDE FACILITY:
All J 4M actuators are supplied with a local visual position indicator (Fig.6).
The OPEN position 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 operating modes, automatic 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” position is selected:
The hand wheel rotates automatically, it is very important not to block it, otherwise the actuator
could suffer unrepairable damages.
The 2 positions are marked:
AUTO = Automatic operation
MAN = Manual operation
