Yaskawa P7B Drive Bypass - Manual (Page 93)

Start Up and Operation 4 - 11
Motor Overload or Customer Safeties Fault Contact Output: Terminals TB1-14, TB1-15 and TB1-16 are a Form C set of
output relay contacts, N.O. and N.C. that are activated when one of the N.C. contacts of the Customer Safety device input
series circuit or the motor overload relay contacts is opened.
120VAC Damper Actuator Output: Output terminals TB1-19 and TB1-20 are provided to energize a damper actuator circuit
or solenoid air valve, typically for outdoor air intake dampers. When the motor is stopped, the output voltage is removed in
order to close the dampers. Whenever the Drive or Bypass is running, the terminals output 120VAC to power a 40VA damper
actuator circuit.
120VAC Control Power Output: Output terminals TB1-21 and TB1-22 are provided to energize additional, customer defined
control logic circuits. A maximum of 100VA control power is available, the user must provide the short circuit protection.
Optional Two Motor “OR” Selection Input: Terminals TB1-23 and TB1-24 are used only when the “Two Motor OR option”
is part of the unit. These input terminals are used for choosing between motor 1 or motor 2 when the optional
MOTOR 1/AUTO/MOTOR 2 selector switch is in the AUTO position.
