Power Connection
Connect the 24 VAC supply voltage (Class 2 transformer only) to the power ter-
minals on the lower left side of the controller.
Connect the neutral lead from the
transformer to the GND terminal and the AC phase lead to the ~ (phase) termi-
nal.
Power is applied to the KMD-5540 when the transformer is plugged in and the
power jumper is in place (see
Illustration 1—Controller Components on page 2
).
Configuration
Prior to operating the KMD-5540, it must be configured using the Hardware Con-
figuration Manager (HCM) application supplied with WinControl. See the Win-
Control XL User’s Manual for additional information.
Note:
All devices on the same network must be configured for the same baud rate.
Operation
Once configured, programmed, and powered up, the interface requires very little
user intervention.
Controls and Indicators
The following sections describe the controls and indicators found on the device.
Network ON/OFF
The network ON/OFF switch is located below the modular jack on the left side of
the controller. Use this switch to enable or disable the RS-485 network connection.
Alternately, you may remove the RS-485 terminal block from the pins to complete-
ly isolate the KMD-5540 from the network.
Status LEDs
Two status LEDs are located on the left side of the controller above the power con-
nector terminal. They are used to indicate the following:
RDY
– The Ready LED blinks rapidly whenever the controller is operating nor-
mally. You can consider this the same as a power LED.
COM
– The Communications LED indicates when the controller is transmitting
over the RS-485 network connection.
Isolation Lamps
Two isolation lamps are located near the Network ON/OFF switch. These lamps
serve three functions:
