TS 870 Transfer  Switch 

 

PM062  REV 11  16/04/19 

                 23 

                                                      Thomson Power Systems 

•

  If the transfer switch was transferring power from the generator source to the 

utility source and the generator switching device failed to open, an auxiliary trip 
relay will trip open the utility power switching device to immediately separate 
the two power sources.

  

If the transfer switch was transferring power from the 

utility source to the generator source and the utility switching device failed to 
open, an auxiliary trip relay will trip open the generator power switching device 
to immediately separate the two power sources. 

NOTE:

  The maximum time period both sources will remain paralleled under 

this failure mode is 200 milliseconds. 

•

  The original source (i.e. prior to the transfer sequence) will remain on load, 

separated from the other source. An alarm light and TSC 900 controller will 
indicate a failure condition which must be manually reset before the transfer 
switch will re-attempt subsequent transfers. For further information on the TSC 
900 features and operation, refer to the separate product instruction manual.  

NOTE:

 Two alarm contacts are provided for the Closed Transition Failure Mode 

(i.e. one for a failed generator power switching device and one for the utility 
power switching device. The contacts are for customer use to remotely trip open 
upstream devices should an abnormal condition persist. 

5.  Transfer Fail Alarm (Switching Device Fail to Close):  The TSC 900 provides a timer 

detect and alarm abnormal operating conditions. Should a power switching device 
fail to close for any reason within a 5-minute time period, an alarm light and alarm 
relay contact will be activated.  For further information on the TSC 900 features and 
operation, refer to the separate product instruction manual. 

5.3. 

DUAL SOURCE ATS 

NOTE:

 This section applies only to Dual Source configured transfer switches. 

ATS may be supplied with the following 3 types of optional Dual Source system configurations: 

•

 

DU

  - 

Dual Utility ATS

: Used for systems consisting of one ATS connected to two 

utilities with at least one  source continually energized to the ATS. ATS will 
automatically switch to the alternate source upon failure of the preferred source. 

•

 

DPG 

-

 Dual Prime Gen ATS

: Used for systems consisting of one ATS connected 

to two generators with one  generator continually energized to the ATS. ATS will 
automatically switch to the alternate generator upon failure of the preferred source. 

•

 

DSG 

- 

Dual Standby Gen ATS (Slave ATS):

 Used for systems consisting of two 

ATS's in a Master/Slave  Configuration.  Refer to the following diagram.  Only the 
Slave ATS is to be ordered and configured with the

 

DSG option. The Master ATS 

is to be ordered as a standard  ATS. The Slave ATS will be connected to two
