12. Slowly turn the fine-tuning potentiometer clockwise (1 or 2 degrees at a time), pausing to allow the Module its necessary response time to detect under-speed. Contin-
ue to turn clockwise until both N.C. safety output contacts (13-14 and 23-24) and indicators turn ON.
13. Increase the motor speed again to normal operating speed.
Both safety output contacts and indicators must turn OFF.
14. To test for the correct setting, slow the motor down below the set value (or turn the motor OFF).
Both safety output contacts and indicators must turn ON again.
15. Wire the safety output contacts into your machine control circuit and verify that the system works according to the requirements.
NOTE: Use the simultaneity potentiometer to adjust simultaneity between the two input channels if only one of them detects the standstill signal from its assigned sensor.
Configuring for Over-Speed Detection
Over-speed detection is detecting a high speed anywhere within the set range of the Module. For this example, we are using 2,000 ipm.
1. Turn OFF power to the Module and the motor.
2. Using a small flat-blade screwdriver, pry open the Module's front plate.
3. Using the DIP switches, select switching range 300-2,700 ipm or 600-5,300 ipm, depending on model.
4. Turn the fine-tune potentiometer clockwise to 10.
5. Set the simultaneity potentiometer to the middle position (0).
6. If the sensors are not yet installed, install them so that they can detect the rotation of the motor.
7. Connect the sensors to the Module.
8. Disconnect the wires from the Module safety output contacts 13-14 and 23-24.
9. Connect power to the Module; the Motor should still be OFF.
The Module's Power LED must come ON immediately. The safety output contacts (13-14 and 23-24) and indicators should come ON after no more than a 3-second
time delay, indicating a standstill condition.
10. Start the motor and run it at the speed you want to detect as over-speed (for this example, 2,000 rpm).
11. Slowly turn the fine-tuning potentiometer counterclockwise until both N.C. safety output contacts (13-14 and 23-24) and indicators turn OFF. (If necessary, fine-tune
the channel simultaneity using the fine-tune potentiometer). This is your switch point.
12. Reduce the motor speed to normal operating speed.
Both safety output contacts and indicators must turn back ON.
13. Verify the proper setting by increasing the motor speed again above the set value.
The safety output contacts must turn OFF.
14. Wire the safety output contacts into your motor control circuit.
Configuration for Zero Speed Detection
These directions illustrate only one setup method, which may be not as accurate as using an rpm meter or an oscilloscope to set the switching frequency to a precise value.
This example should set the switch point very close to Standstill.
1. Turn OFF power to the Module and the machine.
2. Pry open the Module's front plate with a small flat-blade screwdriver.
3. Select the range with the slowest ipm values using the DIP switches (5-40 ipm range for model SSM-FM-11A10 and 10-80 ipm range for model SSM-FM-11A20).
4. Set the simultaneity potentiometer to the middle position (0).
5. Use the fine-tuning potentiometer to set the switch point to the lowest possible value (fully counter-clockwise, to the 1 setting).
6. If the sensors are not yet installed, install them now so that they can detect the rotation of the motor.
7. Connect the sensor outputs to the Module.
8. Disconnect the wires from the Module safety output contacts 13-14 and 23-24.
9. Connect power to the Module; the Motor should still be OFF.
The Module Power LED must come ON immediately. The safety output contacts (13-14 and 23-24) and indicators should come ON after no more than a 3-second time
delay.
10. Start the motor.
The safety output contacts and indicators should turn OFF (safety contacts open), as soon as the motor speed passes the switch point for standstill.
11. Stop the motor.
After the motor speed drops below the minimum switch point value (less than 5 ipm or 10 ipm, depending on model) and after the selected delay time, the N.C. safety
output contacts and indicators should turn ON.
12. If the motor speed does not drop below the minimum switch point value, or if only one of the two channels detects a standstill condition, restart the motor, and increase
the switch point for standstill slightly, by turning the fine-tune potentiometer a few degrees clockwise. Repeat this procedure until both channels detect standstill and
turn OFF both internal relays simultaneously.
13. Connect safety outputs 13-14 and 23-24 to the monitoring circuit and verify that the system works according to the requirements.
