Operation

Test modes

There are 2 methods in which the "Test" mode can be cycled with the test button:

1. Step Test Mode

This method initiates the different components of the unit, one at a time, by temporarily shorting across the two test terminals for two to three seconds. For the initial start- up of the unit, this method allows the technician to cycle a component "On" and have up to 1 hour to complete the check.

2. Auto Test Mode

This method is not recommended for start-up due to the short timing between individual component steps. This method initiates the different components of the unit, one at a time, when a jumper is installed across the test terminals. The unit will start the first test step and change to the next step every 30 seconds. At the end of the test mode, control of the unit will automatically revert to the applied "System" control method.

For unit test steps and test modes, values to cycle the various components, refer to Table 36.
