Electrical Installation: Lights, Ventilation, & Automation (cont.)
Basic relay output wiring (cont.)
Typical 3-wire combination motor starter control wiring (single station)
Interfacing with 3-wire start/stop circuits
With a low voltage SPDT relay, the existing push
button controls can still be used*.
*The addition of an SPDT pilot relay as shown above allows the use of both iPad
®
start/stop and the existing start/stop push buttons.
However, relay contact flight time is critical. If the pilot relay's N.C. contact re-closes too quickly upon an iPad stop command relative
to the motor starter's auxiliary contact opening, the motor starter may fail to de-energize if the iPad was used to energize the starter. If
this occurs, the existing start/stop push buttons must be disconnected from the circuit, and the motor starter must be controlled from the
iPad only as shown below.
