Operation
Adjustment of the open tray dispensers
ATTENTION
Step 1 - Checking the spring adjustment
To test the dispensing height, put a stack of 20 trays (OTA) or 3 trays (OTA-S or OTA/U-BW) on the
stacking platform.
Wait for a reaction.
OTA: If the edge of the uppermost tray is between 35 mm (1.38'') and 50 mm (1.97'') above the upper edge
of the housing, the spring system is adjusted correctly.
OTA-S: The tray dispenser is set correctly when the stacking platform lowers when there are 3 trays on it.
The
upper edge of the uppermost tray must be below the stacking device of the conveyor belt.
OTA/U-BW: The tray dispenser is set correctly when the stacking platform lowers when there are 3 trays on
it. The upper edge of the uppermost tray must be below the stacking device of the dishwasher.
If the stacking platform drops down only a little or not at all, the dispensing height must be altered by adjust-
ing the springs.
If the dispensing height is too high, adjustable springs must be unhooked.
If the dispensing height is too low, adjustable springs must be added.
Step 2 - Altering the spring adjustment
The dispensing height is adjusted or changed by hooking or unhooking the tension springs on two attach-
ment bars within the spring case. For an optimum setting of the spring system, changes at the spring groups
are usually sufficient. If the rear springs need to be hooked or unhooked, the cover of the spring case (OTA,
OTA and OTA-S / U BW) has to be removed.
The springs are arranged in groups of 5: On the front of the attachment bar there are 4 base springs with
higher tension (1) and an adjustable spring with lower tension (2), on the rear attachment bar there are 5
base springs with higher tension(1).

Damage to persons and property due to improper adjustment
When the dispensing height is exceeded, there is a risk of accident or injury
due to tipping of the tray stack. Be careful when taking the stacking platform
out and putting it back in. If it is handled incorrectly, there is a risk of crushing
your fingers.
Adjust appropriately the dispensing height by hooking or unhooking the
springs. When adjusting springs on sharp edges, pay particular attention to
the ends of the tension springs.

Arrangement of the springs
The arrangement of the springs must be symmetrical on the left and right
within the attachment bar, so that it is ensured, that the stacking platform is
guided uniformly and without friction.
