3 Contactor Full Feature Bypass with Disconnect Package (Style B/N) Chapter 2
Customer Connections The 3 Contactor Full Feature Bypass with Disconnect Package is set up to
accommodate the following customer supplied contacts. Contacts should be
rated for 120V AC.
Interlock
The “Interlock” input functions as an Enable input when operating in either
Drive or Bypass mode. Opening of the “Interlock” input (T31-T32) will prevent
the drive/motor from running. T31-T32 are shipped jumpered together (with a
jumper wire) from the factory. If it is desirable to use the “Interlock” input, this
jumper wire can be removed and appropriate customer contacts wired in. If a
valid “Autostart” or “Bypass” contact is present, the drive/motor will immediately
run upon the closing of the “Interlock” input.
Freeze/Fire Stat
The “Freeze/Fire Stat” input functions as a system fault input when operating in
either Drive or Bypass mode. Opening of the “Freeze/Fire Stat” input (T31-T33)
will prevent the drive/motor from running. T31-T33 are shipped jumpered
together (with a jumper wire) from the factory. If it is desirable to use the
“Freeze/Fire Stat” input, the jumper wire can be removed and appropriate
customer contacts wired in. If the “Freeze/Fire Stat” input opens while operating
in Drive mode, the drive will fault and require a manual reset to restart once the
input closes. If the “Freeze/Fire Stat” input opens while operating in Bypass
mode, the motor will coast to a stop and immediately run upon the re-closing of
the input.
Autostart
The “Autostart” input is used to remotely start the drive when SS1 is in the
DRIVE position and SS2 is in the AUTO position. A closed input to terminals
34-35 will start the drive.
Bypass
The “Bypass” input is used to remotely start the motor across the 3-phase AC line
when SS1 is in the BYPASS position and SS2 is in the AUTO position. A closed
input to terminals 34-36 will start the motor.
