The Smart MicroGuard® 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 MicroGuard® 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 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.

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.
