These standard provisions
are designed into the MicroGuard® Metal Box 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. |
