User’s Guide ASCO 5350 2 Lamp test button 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.

To retransfer the load back to Normal go to section 4-2. 5 Flashing light (time delay) Note: The light in the Transfer button flashes when a transfer time delay is active. The faster the blinking, the shorter the delay: 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).
