• PLANT INTERLOCK: This function is used to provide a switch input trip feature similar to the
Local Isolator. When this switch is unhealthy a Plant Interlock Trip will occur. The Plant Interlock
Trip is automatically cleared when the Plant Interlock switch goes healthy.
• LOCKOUT RESET: This function is used to provide a separate reset facility for lockout trips (i.e.
Overload, Ground Fault and Stalled Rotor). These trips are considered to be more serious than
other MM2 trips. When used, this switch will reset Overload Trips (regardless of Lockout Time),
Ground Fault Trips and Stalled Rotor Trips only. All other trips must be reset using the RESET
key. Note that the RESET LOCKOUT USING RESET setpoint in S2: PROTECTION \ MOTOR PROTECTION
OPTIONS allows lockout trips to be reset using the RESET key if required.
• SETPOINT ACCESS: This function is used to provide security against unauthorized changing of
MM2 setpoints. When this switch is unhealthy setpoints cannot be changed from the MM2 key-
pad. When this switch is healthy setpoints can be changed from the keypad. If this feature is not
used Setpoints can always be changed from the keypad.
• AUTO PERMISSIVE: This function is used together with the AUTO START A / AUTO START B
functions and can be further defined using the AUTO PERMISSIVE INDICATION and AUTO MODE set-
points. If the Auto Permissive Switch is healthy, start commands can come from the Auto Start A
/ Auto Start B switches. When the Auto Permissive Switch is unhealthy the Auto Start A / Auto
Start B switches are ignored. When the Auto Permissive Switch is healthy, start commands via
the Start A and B switch inputs and the faceplate are blocked. See AUTO PERMISSIVE INDICATION
and AUTO MODE setpoint descriptions for further functionality.
• AUTO START A: This function is used in conjunction with the AUTO PERMISSIVE function
described above. When the Auto Permissive switch is healthy, the Auto Start A switch can be
used to start the motor.
• AUTO START B: This function is used together with the AUTO PERMISSIVE function. When the
Auto Permissive switch is healthy, the Auto Start B switch can be used to start the motor in appli-
cations where Start B is used (Two Speed and Reversing starter types).
• AUTO PERMISSIVE INDICATION: This setpoint determines whether the AUTO or MANUAL
indicator LED is illuminated when in the auto permissive mode. This allows the AUTO LED to be
used for auto permissive and serial control, or just for serial control.
• AUTO MODE: This setpoint can be configured to either ‘SERIAL’ or ‘HARD-WIRED’. When in
the ‘SERIAL’ mode and the ‘AUTO’ button is pressed, the MM2 will execute start commands from
the RS485 serial link only. When in the ‘HARD-WIRED’ mode and the ‘AUTO’ key is pressed, the
MM2 will execute start commands from the ‘AUTO START A’ and ‘AUTO START B’ switch inputs
only. Note: The ‘AUTO PERMISSIVE’ switch input must be healthy in order to do auto starts. This
setpoint allows the user to change the control mode from MANUAL to HARD-WIRED AUTO via
the AUTO/MANUAL buttons instead of having it done automatically when the Auto Permissive
switch input is put into the healthy position.
• RESET EMERGENCY STOP TRIP: This function is used when a separate Emergency Stop Trip
Reset switch is required. When this switch is healthy and an Emergency Stop Trip is present, the
trip will be reset.
• RESET UNDERCURRENT TRIP: This function is used when a separate Undercurrent Trip
Reset switch is required. When this switch is healthy and an Undercurrent Trip is present, the trip
will be reset.
• TWO WIRE CONTROL: This function is used to provide a means to switch from normal pulsed
three wire start / stop control to maintained two wire start / stop control. When this switch is
