7.5. Wrap the TS-SENSOR loop around all three phases conductors of the circuit. Any imbalance 

will be evident in meter deflection when the range is set to the appropriate setting. The ground 
fault current pulses will be visible in the meter deflection. Analog meters provide easier reading 
during rapid pulsing. The pulse rate may be programmed to facilitate easier readings on digital 
meters. 

 

7.6. When placing the sensor around the three phase conductors make sure that the arrow moulded 

into the sensor loop points downstream (toward the load) in order to provide proper readings. 

 
7.7. Ensure that the junction point of the loop  is held a minimum of 1” away from the conductors in 

order to minimize interference. 

 
7.8. Additional information on the TS-SENSOR is available on the TS-SENSOR data sheet and at 

the address located at the end of this manual.

8.  Pulse Duration 

 

8.1. Pulse time duration may be varied by programming the LOGO logic controller. This is located 

beside the DGF-CT-A. See Figure 5. On the front of the LOGO are four arrow shaped buttons 
and two square buttons labelled “ESC” and “OK”. Modify the pulse time settings by following 
this procedure.
