Overview
The BPX 5600 ships as a combo unit with a heat shrink tunnel. Power enters through the tunnel first — the machine has no independent power inlet on combo units. Follow this sequence every time you power up from a cold start or after transport.
Before You Start
Confirm the following before connecting anything:
- Machine is off the pallet and positioned on the floor
- Tunnel is adjacent and aligned with the machine
- Air supply is available at customer location
- All shipping restraints removed (see Step 1)
Step 1 — Remove Shipping Restraints
⚠️ Do this before connecting the tunnel to the machine. You cannot reach these once the units are joined.
Tunnel conveyor L-brackets:
- Locate the small L-brackets on the tunnel conveyor rail (front of tunnel, left and right sides)
- Remove both brackets and set aside — shipping restraints only, do not reinstall
- If left in place, the front conveyor adjustment knob is blocked and product alignment is impossible
Seal jaw spacers (machine):
- Locate the round
cardboard tube spacersinside the machine — one at each of the three rod corners around the seal jaw area - Pull all three out by hand before powering on
- These prevent the seal jaw from bouncing during freight — they will restrict jaw travel if left in
Shipping strap:
- If a strap runs from the top of the machine down to the base, remove it now
Step 2 — Connect Tunnel to Machine
Physical connection:
- Position tunnel flush against the machine — conveyor ends should align
- Secure with bolts: 2 bolts at top, 3 bolts at bottom
- Tighten all 5 before powering on
Power cable (tunnel → machine):
- Locate the power cable exiting the tunnel (large multi-pin industrial connector)
- Connect to the matching inlet on the machine — typically on the right side panel
- A second cable exits the same area — outbound for standalone use only; leave capped on combo units
ℹ️ Why tunnel first: On combo units, the machine draws power through the tunnel. If only the machine is powered, it will not start. The tunnel must be on for the machine to receive power.
📋 Standalone exception: If the customer already has their own tunnel, the machine can connect directly to mains power using the standalone inlet. Confirm configuration before wiring.
Step 3 — Connect Air Supply
- Locate the
air quick-disconnect fittingon the machine (side panel, near base) - Connect customer air line to the quick-disconnect
- Lift the collar to activate — lift-and-push motion; push only will not seal
- Verify no air leaks at the fitting before proceeding
⚠️ Must lift the collar, not just push. A push-only connection looks seated but won't hold pressure. The seal jaw will not cycle correctly without air.
Step 4 — Connect Optional Bestpack Infeed Conveyor
If the customer has a Bestpack infeed conveyor (72 FB, belted, flighted, or similar):
- Locate the
5-pin plugon the machine — ships pre-installed - Plug is keyed — only goes in one way
- Connect and seat fully — a loose connection causes erratic conveyor behavior
If no Bestpack infeed conveyor is present, leave the plug capped.
Step 5 — Power On
- Go to the rear of the machine
- Locate the
main power switch(rotary disconnect, right side panel rear) - Turn to ON
- Wait for HMI to boot — approximately 10–15 seconds
- Verify no alarm lights on HMI at startup
✅ Expected after boot: HMI touchscreen active, temperature controllers show setpoint values, no alarm lights on panel.
📋 Tunnel heater is separate. The tunnel has its own heater switch on the tunnel panel. Do not turn the tunnel heater on until the machine is running and you are ready to shrink — see the Tunnel Setup article.
Common Mistakes
| Mistake | Result | Fix |
|---|---|---|
| L-brackets left on tunnel conveyor | Can't adjust conveyor position; product runs off-center | Remove before connecting tunnel to machine |
| Air connected but collar not lifted | Seal jaw won't cycle; may show no fault | Disconnect and reconnect — lift collar to lock |
| Power applied before tunnel cable connected | Machine dead — no HMI, no response | Connect tunnel cable first, then power on |
| Cardboard spacers left inside machine | Seal jaw restricted — alarms or fails to reach position | Power off, remove all three spacers, power on |
