Electrical

• To arm the OCR module: The operator must turn the key switch to the REVERSE CAUTION MODE (yel-

low zone), while the parking brake is off.

• To turn the OCR module ON: The module must first be armed, then the orange triangular button is

depressed, illuminating the red LED indicator to indicate that it is ON. It is important that the operator must

take two actions to turn the OCR module ON so that they do not do so inadvertently.

• The OCR module will turn OFF and disarm if: The operator moves the key to any position other than

REVERSE CAUTION MODE or sets the parking brake. If the operator leaves the seat without setting the

parking brake, the engine will turn off. The key movement necessary to re-start the engine will make it

necessary to re-arm and turn on the OCR module if the operator wishes to continue with the ability put the

mower in reverse while the PTO is running.

• To re-arm and turn the module ON: If the key is in REVERSE CAUTION MODE position, it must be

turned to another position (Normal Run), then returned to REVERSE CAUTION MODE. Once re-armed,

the module can be turned on by pressing the orange triangular button. It will be confirmed that the module

is ON by the illumination of the red LED on the module.

Identifying a faulty OCR module

If the OCR module does not function as described, the OCR plug test should be the first step in diagnosis.

• If the OCR plug test confirms that the safety circuits (inputs) work as designed, yet the OCR module does

not work properly, the OCR module is faulty.

• The OCR plug test will give an indication of what the problem is if it is not a faulty OCR module. If the

problem is identified in a particular circuit, check the safety switch that is associated with that circuit. If the

switch is good, then the problem lies within the wiring harness.

NOTE: Like the electronic components found on most cars, the OCR module requires a fully charged battery

to work properly. If the system voltage falls below 12 V, an accurate diagnosis of the OCR module is

impossible because the module will be temporarily disabled by low voltage.
