6.3 Testing the breaker and trip unit
The test functions require no extra equipment, and provide a battery of testing possibilities
via the USB communication. The PXR trip unit has four built-in test modes available for use.
The built-in test modes are secondary injection, simulated, open breaker, and current sensor
continuity. Secondary injection, and simulated test can be configured to optionally open the
breaker. To perform any of these test procedures, a four-digit password, factory set to 0-0-0-0
is required. The password may be changed by the user.
