Event

Features

How do I access the event logs?

To access the event logs:

1. Go to the Group 5 controller and press the
ESC button until the display shows

2. Press Enter/Save Settings, then Menu
Scroll until the display shows

3. Press Enter/Save Settings, then Menu

Scroll to view the events.

How do I communicate with the ATS?

To communicate with the Series 7000 group 5 controller you will need accessory 72E communication
module. With this you can access the group 5 controller to communicate through MODBUS RTU,
MODBUS TCP protocols at 9600 and 19.2K-baud rates. For a detailed discussion regarding
Communication products and application, go to Communications Product s F AQ ’s.

How do I configure the inhibit transfer signal?

Inhibit features are included in the Factory Selectable Features program of the Group 5 controller,
therefore it cannot be modified by the end user. These optional accessories are usually specified by the
customer to be included in the ATS’s upon ordering. If requested for ATS Site, contact ASCO Services
by Dialing 1-800-800-ASCO to arrange a service call.

How do I set the engine exerciser?

To set the exerciser, follow the procedures below:

Is the clock of the engine exerciser accurate?

The engine exerciser clock is moderately accurate. If the generator exercises out of schedule check
the following:

 Verify on the event log that the event recorded was an engine exercise.
 The PRESENT DATE/TIME setting under the engine exerciser menu should be synchronized with

the present date and time.

 The event of engine exercise should fall within any of the enabled P1 to P7 settings.
 The generator should not have its own exerciser program.

After checking all of the above and the problem is still there, contact an ASI service technician.

What is an in-phase monitor?

An In-phase monitor is a motor load transfer feature that monitors the voltage and frequency of the two
sources. It ensures that the voltage and the frequency of the two sources are within acceptable phase
angles (in electrical degrees) before the ATS transfers the load between two live sources to avoid
nuisance tripping on the breakers or physical damage to motors.

How do I specify an ATS?

To specify the ATS, just follow the catalog no. format below:
