Pneumatic Supply (cont)
The system air supply is filtered at F-l and overall system air pressure is regulated by
Regulator R-l. (FOR LOCATION OF COMPONENTS, REFER TO FIGURES 6-l & 6-
2, in the Maintenance section). The air pressure at R-l should be approximately 60 PSIG,
and may be monitored with Pressure Gauge G-l.
Pressure to maintain the slide cylinder (SC-l) in the up (ready- to-crimp) position is
regulated by Regulator R-2. This pressure should be approximately 20 PSIG, and may be
monitored at the Pressure Gauge G-l by depressing the pushbutton switch (PB-l).
Releasing the pushbutton switch results in G-l again indicating R-l air pressure.
Regulators R-3 and R-4 are factory-adjusted to approximately 4 to 8 PSIG to provide low
pressure pilot signals for the slide and crimp complete sensors.
No adjustments should be made unless absolutely certain the adjustment is required.
Indiscriminate changes to regulator or switch settings should not be made. A clean air
supply is imperative to proper system operation. Filter F-l should be drained or changed,
as required.

INITIAL TURN–ON / RESET
Set the LAST PART Switch to the OFF (up) position. Reset occurs any time the operator-
controlled sleeve valve is initially closed, or opened and then closed.
Upon closing the sleeve valve, air pressure is supplied to the PORTA-TAC.
When the sleeve value is closed, the PORTA-TAC cycles to insure that all cylinders are
in the proper position:
- Crimp Cylinder is retracted: V-I OFF
- Transfer Arm is extended (forward): V-2 OFF
- Index Cylinder is extended
- Slide Cylinder is extended: V-3 OFF
- Wire Funnel Cylinders are retracted: V-3 OFF
No contact will be fed to the Transfer Tip. Depressing the INITIAL PART (IP-I)
pushbutton switch momentarily will advance the system to place a contact in the Transfer
Tip.
S-3 is switched on when the Initial Part Pushbutton is depressed.
