DTM Contact Inputs (F/T Relay–Discrete In)
The 5009 control accepts 24 contact inputs. Each of the control’s four Discrete
Termination Modules accept six contact inputs. Of the 24 contact inputs
available, four have functions already assigned to them (preset) and cannot be
changed, the other 20 are user-configurable. The Preset Contact Inputs are:
•
External Emergency Shutdown
•
External Reset
•
Raise Speed Setpoint
•
Lower Speed Setpoint
The control will initiate an emergency shutdown any time the External
Emergency Shutdown contact input is opened. This input is typically tied into the
system’s trip string. Before starting, the External Emergency Shutdown input
must have an external contact or switch wired to it and it must be closed. The
external reset contact can be used to remotely clear latched alarms and trip
conditions. The raise and lower speed setpoint inputs can be used to remotely
raise and lower speed or load.
Applications requiring external contact inputs must have the desired function
assigned or configured to a specific input. Refer to Volume 3 of this manual for a
complete list of programmable contact input options. If the 5009 control is
configured for a generator application two of the contacts must be configured for
the Generator and Utility breaker inputs. The Generator Breaker contact must be
wired so it is closed when the generator breaker is closed. The Utility Tie Breaker
contact must be wired so it is closed when the utility tie breaker is closed.
Contacts must change state for a maximum of 40 milliseconds and a minimum of
20 milliseconds for the control to sense and register a change in state.
