Strength/Prog Light Emitting Diode (LED)
In normal operation this Light Emitting Diode (LED) will emit green, yellow, or red light. If
the LED is green, the TCV is receiving a strong radio signal from the FM Switch Wrench
that it is working with. If it is yellow the signal strength is marginal. If this LED is red than
the signal strength is inadequate and the distance from the tool to the TCV should be
reduced. During programming this LED will be lit continuously to indicate the unit is in pro-
gramming mode.

Key
Lock
The Key Lock permits and denies access to programming the unit. When
the Key lock is in the PROG position, programming functions are
enabled. When the Key Lock is in the LOCK position, the unit is in the
normal operating mode and only those functions are accessible.

Power Entry Module
The Power Entry Module houses the Receptacle
for the Power Cord, the Voltage Selector and Fuse
Holder, and the Power Switch.
9
Receptacle
The Receptacle accepts the female end of the
supplied Power Cord. The pronged end must be
plugged into a grounded outlet.
10
Power Switch
The Power Switch permits and denies electric
power to the TCV.
11
Voltage Selector/Fuse Holder
The Voltage Selector/Fuse Holder permits using
the TCV with either 115 VAC or 230 VAC electric
power sources. The correct power source must be
selected during the installation process and before electric power is supplied to the unit.
12
RS232 Communications Port
This port provides connection for the RS232 cable supplied
with the unit. The TCV is programmed with the supplied
software, and must be connected to the computer through
this port.
13
5-Pin Communication Receptacle
This receptacle mates with the supplied 5-pin connector,
and is used to communicate with programmable logic con-
trollers (PLC) and other devices.
