the slide adjust screen or when a stored job is recalled and the system is “ON”. Note that the “AUTO ADJUST” key will only appear when the slide adjust switch is ON and the editing cursor is on the slide adjust setpoint of a slide adjust system. An auto adjust sequence always approaches the slide setpoint from above. For instance, if the current position is 10.000 and the slide setpoint is 12.000, the auto adjust sequence might take the slide first to 12.015, then back to 12.004, and then “pulse” the slide the last four thousandths into position. This is to ensure consistent setups by taking up gear lash from the same direction every time. Note that a slide setpoint of 00.000 (used to store a job that will not

overwrite the previous slide setpoint on recall), will prohibit automatic adjustment. Automatic movement is subject to the following conditions:

a)The slide adjust switch must be on.

b)The press must be stopped.

c)The press must be at the top of the stroke.

d)The hydraulic overload on the press, if present, must not be tripped.

e)The Link Master Control (LMC) relay must be engaged.

f)There must be no faults in the slide system and the counterbalance system, if present.

g)The auto adjust sequence for the slide will not start until the counterbalance system, if present, is at least up to its pressure setpoint. If the correct pressure setpoint for the counterbalance has been entered, this will ensure that the counterbalance has taken up any clearances in the slide connection system to increase accuracy of shut height adjustment. When the slide adjust system waits for the counterbalance system to finish adjusting to its pressure setpoint, the status message of the slide adjust system will be “Waiting for Cntr-Bal”.

NOTE! A counterbalance pressure that is far too low or far too high during any shut height adjustment may place excessive load on the shut height adjust motor and may even stall the motor. This condition can also occur with non-automatic motorized slide adjust systems. If the automatic slide adjust doesn’t see slide adjust movement within two seconds of a command to move, it will stop its command to move and generate the Fault message “Slide Did Not Move”.

IMPORTANT! Automatic movement will be terminated if the ESTOP button, “JOG UP” softkey, “JOG DN” softkey, or “CANCEL AUTO ADJUST” softkey is pressed while the slide is moving automatically. Automatic movement will pause if the slide adjust switch is turned off. It will resume when the slide adjust switch is turned back on.
