LINK Systems OmniLink II Press Automation Control - Manual (Page 107)

August 30, 2002 Manual Version 1.0 6.2
If the monitor detects a process fault, a stop signal will be sent to the press control. There are three
types of stops than can be assigned to an individual channel. When an input malfunction is detected, a
cycle stop, top stop, or intellistop signal can be asserted. If programmed for a cycle stop and a
malfunction is detected, a stop signal will be immediately sent to the press control. If programmed for a
top stop and a malfunction is detected, a stop signal will be sent to the press control at a slide position
that will allow the slide to come to rest at the top of its stroke. If programmed as an intellistop and a
malfunction is detected, an immediate stop signal will be sent to the press control if the slide can come
to rest before a programmed critical angle. If the malfunction occurs at a slide position that will not
allow the slide to come to rest before the programmed critical angle, a top stop will be executed.
The system has the capability of displaying extensive channel diagnostics. The current state of each of
the channel inputs is displayed. In addition, a numerical and graphical representation of the channel
input’s history is available. The last 64 transitions (a transition is either a change in sensor state from on
to off or from off to on) of the channel input are stored. This information can be displayed numerically
in a table format or graphically.
The Digital Die Protection and Process Monitors have a power supply that can be used to power sensors.
This supply provides 24 volts DC @ 1 Amp.
Section 6.2 Specifications for the Digital Die Protection and Process Monitors
There are several different versions of the Digital Die Protection and Process Monitor. The Model 5120
is a 16 input unit. The Model 5121 is an 8 input unit. Each model is available with or without a 19 pin
Quick Die Change Receptacle. When the Quick Die Change Receptacle is available, all of the unit’s
inputs are accessible via this connector. A single cable can be used to attach the die sensors to the inputs
of the Digital Die Protection and Process Monitor. The Model 5120 is available with or without the front
panel micro connectors and binding posts. The various models and their part numbers are listed in Table
6.1.
