7.3) AUTOMATION INSTALLATION
Depending on the arm type to be used and on the automation fastening
position, refer to the relevant installation table (para. 5.1 to 5.6), which
specify the points where you must drill the holes required to install the
automation and the pulling arm.
For the assembly of the arm, refer to paragraph 6.
To fasten the devices, use suitable screws and fixings.
After fastening the automation and arm, follow the next steps to connect
the arm pin to the shaft output of the Neptis Plus automation.
7.4) CHOICE OF THE SPRING LOAD (FOR NEPTIS PLUS
NB-LET, NB-LETB, NB-SLT, NB-SLTB AUTOMATIONS
ONLY)
The closing spring is factory-preloaded to a standard value, which is
indicated by the alignment of the red line on the belt with the red mark
on the pulley.
Select the spring re-closing force according to the following rule:
• Connect the arm to the automation output shaft with the leaf
completely open to obtain a low re-closing force (minimum spring
load).
• Connect the arm to the automation output shaft with the leaf in an
intermediate position to obtain a medium re-closing force (medium
spring load).
• Connect the arm to the automation output shaft with the leaf
completely closed to obtain a high re-closing force (maximum spring
load).
7.5) INSERTION OF THE ARM TAPERED PIN
Make sure that the plastic plate is inserted in the mechanical
body of the automation, where the output shaft is located,
before inserting the arm pin.
The arm pin has some joints that must perfectly mesh with those existing
in the automation output shaft; their function is ensuring that the arm pin
always moves integrally with the automation motion transmission shaft.
Insert the arm pin into the output shaft of the automation, making sure
that the joints on the two parts mesh properly, then tighten the arm pin
setscrew to a torque of 19Nm.
Only for NB-SMT, NB-SMTB Neptis Plus automations
without spring
If the leaf moves properly throughout its stroke, both when opening and
when closing, proceed with the electrical connections as described in
the Electronics section, in paragraph "Electrical connections".
for Neptis Plus NB-LET, NB-LETB, NB-SLT, NB-SLTB automations
only
Follow the steps described in the next chapter.
7.6) SPRING RELEASE (FOR NEPTIS PLUS NB-LET, NB-
LETB, NB-SLT, NB-SLTB AUTOMATIONS ONLY)
During this operation the automation pulleys and the arm may
start moving; move your fingers or other body part away from
the moving components during this operation and keep the
leaf manually locked.
