Start-Up; Before Power-Up; With Power On - SAF Opal Pro MS6 Series Installation & Operating Procedures

MS6 REDUCED VOLTAGE STARTER

5.5 START-UP

5.5.1 BEFORE POWER-UP

• Ensure that all electrical connections are completed as shown on the schematics, and that
connections are properly tightened. Including a solid ground connection.

5.5.2 WITH POWER ON

• Check 120VAC control voltage to terminals 1 & 2 of the Opal Pro
• Set parameter 1001 to the control scheme desired
• Set parameter 1002 to the ramp time desired (set to 0 for constant current mode)
• Set parameter 1003 to step current required (set to required current for constant current
mode)
• Set group 11 parameters for desired stopping method and setup
• Set parameter 1301 to motor full load current as read from the motor nameplate
• Set parameter 1302 to the motor nameplate voltage
• Set parameter 1303 to the motor nameplate service factor
• Set group 14 parameters if a communication module is installed on the Opal Pro
• Set group 15 parameters for the desired fault conditions
• Check for the red LED on the keypad to be NOT illuminated (if it is illuminated there is a
fault which will be shown on the LCD display of the keypad)
• Check for the green LED on the keypad to be illuminated (if it is not, the ENABLE signal
(terminal 8) is missing or there is a problem with the incoming 3 phase power)
• Once start has been initiated the motor must start rotating immediately, it must not stall. If
it does not rotate immediately the step current (parameter 1003) must be increased
• Parameter 1002 can be adjusted to extend or decrease the acceleration time. The actual
motor accelerating time depends on the motor current as well as the mechanical load. The
acceleration time entered is the amount of time it will take for the current to increase from
the step setting to 500% of the nameplate current
