Logic Terminal Strip Wiring—Standard Controller
General Logic Input Information
The logic inputs, Terminals 2-7 & 9, are switched by a
current sinking path to Logic Common. They can be switched
by mechanical switches, relays, or NPN transistor outputs.
Logic input terminal voltage is approximately 12 VDC, and
4 mA of current are conducted through the switch to Logic
Common.
Program Select Inputs (Terminals 3, 4, and 5)
These inputs determine which program in the current
program bank is controlling the outputs. When any of these
inputs are connected to Logic Common, they take priority
over the keyboard selected active program (FCN 3). If these
inputs are being used, make sure that the FCN 3 active
program is set to 1. Input combinations are:
PRG # 1 2 3 4 5 6 7 8
SEL 1 off on on off off on on off
SEL 2 off off on on on on off off
SEL 3 off off off off on on on on
Master Program Enable (Terminal 6)
When the Master Program Enable input is switched to Logic
Common, all programming operations are accessible. A
key switch is commonly used for this input to prevent
unauthorized personnel from accessing the more
complicated features of the control. A temporary jumper can
also be installed for initial programming at the master level,
and then removed when this programming is completed.
Output Group 1 Enable (Re-Zero Input) (Terminal 7)
On standard 5XX1 controls, switching this input to Logic
Common instantly changes the control's position to zero
degrees. The position re-zeroes off of the leading edge of
the signal, but is not held at zero while the input is energized.
When the controller is de-energized, the controller position
will revert to the offset value programmed in FCN 2.
On models PS-5004, 5104, 5024, and 5124 this input is the
enable input for output Group 1. There are four programmable
modes of operation available for enable inputs. For more
information see the Output Grouping and Enable Modes
section in the Appendix.
Motion Detection Output (Terminal 8)
This is a sourcing output signal that is on whenever the
current machine speed is within or equal to the Low and
High RPM setpoints (FCN 1, page 4-7). The circuit is
basically a 12 VDC supply being sourced through a 470
ohm resistor. It is typically connected to PLC inputs or
external solid state output modules. Because the 5000
Series controls have Motion ANDing, any of the standard
outputs can be programmed to be on whenever the motion
logic is on. This is an alternative to the Motion Output when
it is not compatible with an input circuit or if a higher voltage
or current needs to be controlled.
Operator Program Enable (Terminal 9)
When this terminal is switched to Logic Common, access to
programming at the Operator level is enabled. A key switch
can be used to control who can make program changes at
the Operator level. Operator access can also be enabled
through a keyboard enable code number.
12 VDC Power Output (Terminal 10)
The 12 VDC accessory power supply is regulated and
capable of supplying up to 150 mA. It is protected by a 1/4
amp fuse which is located just below the Logic Terminal
strip. This supply is intended to be used for electronic
sensors or other electronic circuitry. It should not be used to
power relays or any other inductive devices. Logic Common
(terminals 1 or 2) is the negative side of this 12 VDC supply.
