Two Hand Relays
Minotaur MSR7R & MSR7C
Specifications
Description
The Allen-Bradley Guardmaster Minotaur MSR7R & MSR7C are logic
units for monitoring and interfacing two hand control devices with a
safety related circuit. The MSR7R is for use with mechanical
switches and the Allen-Bradley Bulletin 800Z Zero Force Touch
Buttons. The MSR7C is for use with electronic-sensing (for example,
capacitive or photoelectric) palm buttons because the MSR7C will
not turn its output ON if a power interruption occurs while a
person’s hands are on the buttons.
The MSR7 has 3 N.O. safety outputs and 1 N.C. auxiliary output.
The safety outputs have independent and redundant internal
contacts to help ensure the safety function. The auxiliary contact is a
nonsafety output intended to provide an external signal about the
status of the safety outputs.

The MSR7 requires the two switches to be operated within
0.5 seconds of each other and will only authorize the ON state while
both switches are held down. If one of the switches is released, the
output goes to the OFF state and the machine cannot be restarted
until both buttons are released and then operated simultaneously.

The MSR7 conforms to EN574 which gives specific requirements
for two hand control units and logic devices. Categories IIIB or IIIC
are achieved depending upon the wiring.
