Control Terminal
Designations
As shown in Figure 3.9, the SMC Dialog Plus controller contains 20
control terminals on the front of the controller.
Figure 3.9 SMC Dialog Plus Controller Control Terminals
Do not connect any additional loads to these terminals. These “parasitic” loads may cause problems with operation, which may result in false starting and stopping.
When control power is absent from terminals 11 and 12, this contact will be normally open. Upon application of control power, the contact will take the state, normally
open or normally closed, as programmed.
Grounding
Provision
Provision for connecting a field installed grounding conductor is
provided on each controller. It is shown in Figure 3.10 and is located
on the heatsink. This symbol is the ground connection identification
symbol as defined by IEC Publication 417, Symbol 5019.
If the protective conductor is not connected to the heatsink, the
plating and/or paint must be cleaned from the four mounting holes or
four star washers (tooth lock washers) must be used.
