2.6 TESTING PROCEDURES
This section provides reference tables to check the circuitry for TMP4100-Series marking heads.
2.6.1 Stepper Motor Resistance
The following information is provided to check the resistance values of the stepper motor circuit.
1. Remove electrical power from the marking system.
2.
TMP4100, TMP4150, TMP4155: Remove air pressure from the marking system.
3. Disconnect the marker cable from the controller.
4. Measure the resistance values for the stepper motor at the connector on the end of the marker cable.
Refer to Table 2-2 for acceptable values.
