Lower End Limit (401)
The Lower End Limit function is used to program the lower end limit of the shut height
opening. This can prevent the ram from accidentally exceeding its mechanical adjustment
capabilities. If the shut height reaches or goes below the value programmed in this function,
the lower limit relay will de-energize and the lower limit LED will turn on. This can cause
power to be taken away from the press’s ram adjust motor(s) if the lower limit relay is properly
wired. (For wiring instructions, see Section 3.2: Wiring.) The default for this function is 0.000
inches. This value can range from 0 to 999.999 inches. To program a value for the Lower End
Limit function, perform the following steps:
1. Select the function key.
The monitor displays “F-----”
2. Enter function number 401. Select the enter key.
The monitor displays the function’s current value.
3. Enter the new value. Select the enter key.
NOTE: To temporarily regain lost power to the ram adjust motor(s) (close the lower end limit
relay) if the shut height reaches or goes below the lower end limit, see Relay Override.
Relay State (402)
The Relay State function is used to program the monitor’s upper and lower limit relays to either
energize or de-energize when the monitor is in normal machine operation. Either a 0 or 1 can
be programmed in this function. Entering a 0 will cause the monitor to energize the relays
during machine operation, and de-energize the relays when a limit is exceeded or when an error
occurs. Entering a 1 will cause the monitor to de-energize the relays during machine operation,
and energize the relays when a limit is exceeded or when an error occurs. The default for this
function is 0. To change the state of these relays, perform the following steps:
1. Select the function key.
The monitor displays “F-----”
2. Enter function number 402. Select the enter key.
The monitor displays the function’s current value.
3. Enter either a 0 or 1. Select the enter key.
