Checks And Setting; Oil Level Check; Adjusting The Operator - Aprimatic ZT40 4M Instrucciones Para La Instalación

Installation / Finals operations
Press on the upper casing (E12 pos. 1), securing it
with the screw (E12 pos. 2), using a cross-headed
screwdriver.
When completely assembled, the operator should
appear as in the illustration (E13 pos. 3).
!
Warning
To gain access to the release key, it is enough to
slide back the hatch (E13 pos. 4); after locking
or releasing operations, remember to close the
hatch again.
After installation, an appropriate warning sign must be
attached to the gate (E14 pos. 5).
4.1 CHECKS AND SETTINGS

4.1.1 Oil level check

Check the oil level by looking inside the operator from
the release fl ange with the plug removed, when the rod
is completely withdrawn.
The oil level should be a few millimeters below the
surface of the aluminum casing.
!
Warning
Use only AprimOil HC 13 for topping up.

4.1.2 Adjusting the operator

With the gate leaf moving, measure the thrust force
at the end of the gate leaf, using a dynamometer (D3
pos. 2). The thrust force must never exceed 15 kg
(147 N). If necessary, adjust the working pressure
of the operator.
Using a broad, fl at-headed screwdriver, turn the control
valve clockwise to increase the pressure and anti-
clockwise to reduce it.
The settings are made both on the opening control
valve (silver - D4 pos. 3) and the closing control valve
(gold - D4 pos. 4).
Caution
• In A-type operators, the gold coloured valve sets
the opening pressure and the silver one sets the
closing pressure.
• The opening thrust of the gate leaf should be set
slightly higher than the closing thrust.
• After making the settings, make another check
with the dynamometer to see if the thrust force
corresponds to the setting; if it doesn't, then the
setting needs to adjusted again.
• If the gate leaf requires an excessively high
pressure to move it, then make another thorough
check of the mechanical parts, the plumb and the
free movement of the gate leaf itself.
