3 close to operate the HDV 3 Pull
Pressure solenoid, allowing fluid through
the HDV via outlet port P. Normally closed
Relay contacts R3-2 open, preventing
Return Pressure HDV solenoid from
operating while the pull pressure HDV
solenoid is energised.
The Installation Tool Piston moves
rearwards to begin the Fastener
installation cycle
When the Swage Pressure reaches the
pressure set on the Digital Swage
Pressure Switch 6 Relay R4 energises
and latches in via Relay R1-3 and Relay
R4-2 contacts.
Normally closed Relay R4-1 contacts
open and de-energises Relay R3.
R3-3 contacts open to de-energise the
HDV Pull Pressure solenoid.
Relay R3-2 contacts close to energise the
HDV Return Pressure solenoid allowing
fluid through the HDV outlet port R
The Installation Tool Piston moves
forward.
When the Piston reaches the fully forward
position, pressure in the return line
increases and opens the Digital Return
Pressure Switch 7 which de-energises
Relay R1. This also de-energises the HDV
Return Pressure solenoid. The Digital
Return Pressure Switch then recloses (re-
closes-sets).
The installation cycle is now complete
Notes:
1. The latching of Relay R3, allows the
fastener inst allation to continue even if the
Limit Switch cont act s in the T ool open
after activating the Tool Trigger.
Principle of Operation with Bobtail Tools
Non Bobtail Tools
When the tool trigger is depressed :-
Relay R2 is energised which also
energises Relay R1 via contact R2-1
(latched in by the Digital Return Pressure
Switch 7).
Normally open Relay contacts R2-3 closes
to operate the HDV 3 solenoid, allowing
fluid through the HDV via outlet port P
Normally closed Relay contacts R2-2
open, preventing the Return Pressure
HDV solenoid from operating while the
pull pressure HDV solenoid is energised.
The Installation Tool Piston moves
rearwards to begin the Fastener
installation cycle.
When the Installation Tool trigger is
released, Relay R2 is de-energised,
contacts R2-3 open to de-energise the
HDV Pull Pressure solenoid. relay
contacts R2-2 close to energise the
Return Pressure solenoid, allowing fluid
through the HDV via outlet port R.
The Installation Tool piston moves
forward.
When the Piston reaches the fully forward
position, pressure in the return line
increases and opens the Digital Return
Pressure Switch 7 contacts, which de-
energises Relay R1. This also de-
energises the HDV Return Pressure
solenoid and the Digital Return Pressure
Switch then recloses (re-closes-sets).
The installation cycle is now complete.
Bobtail Tools (when connected to the
Powerig via the Multi-Pin Lemo Plug)
When the Bobtail Tool Limit Switch is
activated (LED Light on ), and the Tool
trigger is pressed, Relay R3 is energised
(and latched - see Note 1). which also
energises relay R1 via contact R3-1
(latched in by the Digital Return Pressure
switch). Normally open Relay contacts R3-
