ASCO 5350 ATS Remote Annunciator

Operation

The ASCO 5350 ATS Remote Annunciator communicates with ASCO automatic transfer switches (ATSs) to report their status. The ATS Annunciator polls each ATS and obtains its status. Lights indicate which ATSs are connected to the normal source or emergency source. Source acceptability status for each ATS is also shown. In addition, the ATS Remote Annunciator can send commands to individual ATSs to control their operation.

A control key switch prevents unauthorized operation.
Transfer test buttons (one for each ATS) simulate a normal source outage and transfer the individual loads to the emergency source, if acceptable. The same buttons are used to retransfer the load back to the normal source. When the buttons are held, any active time delay is cancelled. Lights in the buttons indicate which ATS is in the test mode and if a time delay is active.

Control key switch

The Control key switch prevents unauthorized operation of the ATS Remote Annunciator. The key can be removed in either the locked or unlocked positions. In the locked position (left), the buttons do not operate. In the unlocked position (right) all buttons function.

Lamp test button

Press and release the lamp Test button to briefly turn on all lights; they will go off after a few seconds. This operation verifies that all the lights work on the ATS Annunciator.

Alarm silence button

Press and release the alarm silence button to turn off the audible alarm sound. This action also opens the alarm relay contacts. Do not hold the button. These are the possible alarm conditions:

Before using the transfer button, be sure conditons are safe for running the generator and for load transfer.

Transfer test

The following operation starts the generator and transfers the load. Be sure that conditions are safe to do this operation.

4-1 Load Transfer to Emergency source

To transfer the load from the normal source to the emergency source, follow this procedure:

1. Turn the Control key right to the unlocked position.
2. Select ATS that you want to operate (by ATS no. or name).
3. Press and release the Transfer button below the selected ATS (do not hold the button).
4. Observe that the E light comes on (generator acceptable).
5. Observe that the light in the corner of the button blinks (transfer time delay active, if used).
6. Observe that the ATS connected lights change position (transfer from normal to emergency)
7. To retransfer the load back to Normal go to section 4-2.

Note:
If Feature 2B transfer to emergency time delay is used, the transfer may not occur for up to 61 minutes (depending upon the ATS and the setting in the controller).
To bypass (cancel) this time delay, press the Transfer button again and hold it for more than 5 seconds until you hear a beep.

Load Retransfer to Normal source

To retransfer the load from the emergency source back to the normal source, follow this procedure:

1. Turn the Control key right to the unlocked position.

3. Press and release the Transfer button below the selected ATS (do not hold the button).
4. Observe that the N light comes on (utility acceptable).
5. Observe that the light in the corner of the button blinks (retransfer time delay active, if used).
6. Observe that the ATS connected lights change position (transfer from emergency to normal).
7. Turn the Control key left to the locked position, then remove it.

Note:
If Feature 3A retransfer to normal time delay is used, the transfer may not occur for up to 61minutes (depending upon the ATS and the setting in the ATS controller).
To bypass (cancel) this time delay, press the Transfer button again and hold it for more than 5 seconds.

Note: Alarms can be specific to ATSs or a general communications error or any configured alarm via the Power Manager.

Flashing light (time delay)

The light in the Transfer button flashes when a transfer time delay is active. The faster the blinking, the shorter the delay:

Reset button

A hidden reset button is located just below the Control key switch (see Figure 1). The Control key switch must be unlocked. The reset button and alarm silence button work together as follows:

Soft reboot reset (keeps user’s configurations)

The soft reboot retains the configurations that you have made.
To perform a soft reboot, press and hold the hidden reset button and the alarm silence button together for no more than 3 seconds. The configuration parameters remain unchanged.

Hard reboot reset (factory default configuration)

The hard reboot resets all user configuration parameters to factory default settings. The configurations that you have made will be erased. To perform a hard reboot, press and hold the hidden reset button and the alarm silence button together for more than 15 seconds. The default configuration parameters are:

Other factory default parameters could be checked through Ethernet interface with computer.

Troubleshooting

Restore the DC or AC power supply. Check the terminals, fuse, circuit breaker.
