The
Smart DIN-Rail Controller makes machine guarding safer,
easier to use and will enhance machine utilization measurably.
It is unique in the machine guarding industry for the ability
to constantly display the operating conditions of the safety
light curtain. The Controller informs the user of any faults,
failures and the current operating status of the safety system
in plain English on the external message display center. The
message display is located on the front panel of the
Controller. This gives the machine operator and front line
supervisors access to information quickly and
safely.
The
DIN-Rail Controller diagnostic message display will
provide all faults related to redundant circuitry,
microprocessors, captive contact safety relays, bad grounds,
external infrared sources, shorts, blanking functions, etc. The
Controller will also display on the message center the
locations of misaligned or obstructed beams and then count and
display how many beams have been obstructed. Additionally, if a
printed circuit board or component should fail, the faulty
board and beam number will be shown on the display. The board
then can be replaced quickly in the field, eliminating costly
downtime.
The counting and displaying the number of
beams blanked out is required information when
determining the depth penetration factor for proper
installation of any light curtain.
ANSI
B11.19-1990.
These standard
provisions are designed into the DIN-Rail Controller
Module to facilitate any guarding system interface and
monitoring desired. Usage is optional.
CINCINNATI
INTERFACE - with Red LED
Indicator
or Emergency Stop Input
(optional)
Description: This is provided to allow an external device to
determine if the light curtain is still capable of shutting
down the safety control circuit. The Cincinnati Interface
allows an external device to override the light curtain and
initiate a RED condition and open up the standard output relay
contacts.
Application: Cincinnati Press, PLC
EXTERNAL RELAY CHECK- with
Green LED Indicator
Description: The Pinnacle External Relay Check allows the
MicroGuard® to monitor a pair of external relays in series
using the external relays secondary set of DRY contacts,
provided that they are N.C. force-guided contacts. The captive
or force-guided contacts will maintain the identical position
as the primary set of contacts on the external relays, except
that the secondary set of contacts are wired up to signal the
reverse of the primary. (i.e., primary are N.O., secondary are
N.C.). The circuit looks for both closing and opening of the
external relay contacts. The Microguard® system is a safe
external relay check.
Application: Monitoring external relay contacts for shorts or
opens.
EXTERNAL VOLTAGE CHECK
PROVISION - with Green LED Indicator
Description: The External Voltage Check allows for the
MicroGuard to monitor voltage coming from any outside source as
a condition for keeping the light curtain GREEN. This option is
very similar to the External Relay Check, except that this
operates with high voltage so that it can be used to monitor
other devices besides relay contacts.
Application: Monitor voltage at a solenoid, relay,
etc.
AUXILIARY OUTPUT CONTACT
PROVISIONS
Description: The Auxiliary Output Contact option provides both
a N.O. and N.C. isolated (DRY) contact output to signal the
condition of the light curtain. The output is used in
conjunction with the standard pair of output relays that are
wired to the safety circuit of the equipment.
Application: Signal to PLC, etc.
DATA INPUT/OUTPUT FOR USE WITH REMOTE PLC
OPTION
Description: This option allows the user to specify up to four
signal lines as either input and/or output lines for issuing
remote commands to the MicroGuard® and/or sending commands to a
PLC.
Application: Use this option if you need to know object size,
or to use your PLC to program Auto-Blank, Floating-Blank, reset
"Penetration," adjust guarded area, etc. This option is
programmed at the factory for the user and is
custom.

Output
Circuitry
Safety Output
Configuration
Every MicroGuard comes standard with two
Captive Contact Safety Relays, auxillary relay,
and fault relay. The metal box controller can
be configured for a “Single Stop” circuit or a
“Dual Stop” circuit output.
Single Stop Circuit SS
- Both internal Safety Relays are wired in
series and the user is provided with one dry
contact output. (Open when fault or blocked.)
Supplied standard on the Metal Box (MG)
Controller.
Dual Stop Circuit DS -
Each internal Safety Relay is wired separately
which provides the end-user with two separate
dry contact outputs. (Both open when fault or
blocked.) Add suffix DS to Metal Box (MG) part
number.
The DIN-rail controller comes configured for a
Dual Stop circuit with a jumper wire between
outputs so that the user can wire into a Single
Stop circuit system provided they wire both
Safety Relays in series.

|
WARNING
- Both safety relays in the
dual stop configuration must be wired
into the machine isolated stop
circuits of the machine
control.
