ALIGN XCS RAIL
1. Verify that the edge rail system is aligned and adjusted parallel within specification.
2. Use a gauge block and feeler gauges or a pair of calipers to measure the distance from the fixed edge rail
to the XCS rail near each of the feedscrew locations: (onload, offload, and intermediates). The measured
width at all feed screws must fall within a .020 (0.5mm) range.
3. If adjustment is required de-couple the wormgear boxes at the rear of the machine from the width adjust
shafts to allow turning one feedscrew at a time. Adjust feedscrews by hand to bring the XCS rail location
into specification then reconnect the width adjust shafts.
4. Verify XCS parallel in the spans between the feedscrew locations. The distance from the fixed edge rail to
the XCS rail midway between the feedscrew locations must be within .052 (1.32mm) of the measurement
at the feedscrews. XCS parallel can not be adjusted at the gantry locations. Replace the XCS rail if
variation is excessive.

INSTALL XCS CHAIN
Note: The XCS chain is custom manufactured as a pitch matched set with the fixed edge rail chain. Do not mix or
splice these chains. Always replace both chains as a set.
1. Feed the XCS chain into the offload end of the XCS rail until it reaches the opposite end of the machine.
2. Continue to thread the XCS chain over the sprockets at the on-load end then feed it back under the oven.

3. Thread the XCS chain through the tensioner trolley at the center of the return loop. The XCS tensioner
trolley is properly oriented when its extension spring is beneath the large sprocket.

4. At the off-load end of the oven, thread the XCS chain through the sprockets. Reconnect the master link.
Make sure the closed end of the keeper clip is facing the direction of conveyor travel.
5. Check that the XCS chain is properly engaged with all of the sprockets and is not hung up or twisted
anywhere on top or underneath the oven.
SET XCS TENSION
Caution: Excessive tension in the XCS system will accelerate wear of the XCS chain.
1. Run the conveyor through several revolutions to ensure the XCS chain is properly settled.
2. The XCS tension is adjusted at the onload end of the machine by moving the XCS drop arm. The arm is
fixed by a slotted link. Use a 5/32 hex key and loosen the clamp screw to reposition the arm.
