Figure 3.7 – Two-Wire Control

Three-Wire Control

If using three-wire control, the CLOSE contactor input is maintained

high using two contacts. Momentarily opening this input will cause the

IntelliVAC to open the contactor. Momentarily closing the START

contact will provide a CLOSE command to IntelliVAC (given that all

permissives are satisfied).

In this configuration, the STATUS output acts as a seal-in contact. If a

fault occurs, in addition to cycling control power over to the IntelliVAC

module, the CLOSE command must be removed for a minimum of 4

seconds before being re-applied. Refer to Figure 3.8.

A T T E N T I O N

For Emergency Stop applications requiring

removal of power, a contact should be placed in

the “L1” control power rung to the IntelliVAC.

If the TDUV feature is used, the contactor will

not open until the programmed TDUV time

has expired.

* Refer to Table 3.A for recommended fuse sizing.
