For manual operation of the test system (e.g. with test pistols according to EN 50191 or for maintenance and calibration work), the safety circuit must be equipped with 3 jumpers. Closing of the safety circuit is then done manually via the "LOCK" button on the front panel of the device.

Built-in jumpers:

• Outputs E1, O6,O7,O8
