This is a four-digit number that must be entered in the Program
Mode Access function in order to put the monitor in either
program mode or supervisory mode. There are two types of access
codes: program mode and supervisory mode.
A group of functions used to calibrate the monitor's input device.
These functions can only be programmed when the monitor is in
program mode.
This module contains a Central Processing Unit (CPU) which is
used to process data it receives from the resolver. It then shows the
position of the shut height on the monitor's LED display.
Located on the power supply module, this relay consists of a pair
of N.O. contacts. During normal machine operation, this relay
is energized. If an error occurs during machine operation, the
controller will de-energize this relay. This relay should be wired to
the machine's safety interlock.
This module is used with a Linear Displacement Transducer
(LDT). This module provides +24VDC to supply power to the
LDT and interface for the RS-422 output signal.
Located on the relay output module, this relay consists of one
pair of N.O. contacts and one pair of N.C. contacts. This relay
is programmable to de-energize when the machine's shut height
moves below the programmed lower end limit.
This module supplies power to the monitor. It also contains the
fault check relay and an auxiliary input. The auxiliary input is used
for either the movement detection or position hold feature.
A mode of operation the monitor must be in before a function can
be programmed. The Program Mode Access function is used to put
the monitor in program mode.
The method used to improve the resolution of an LDT. The "on"
time of a pulse width output is multiplied by a specifi ed factor.
This multiplication provides more counting time for the counter,
