4.7 Connecting a foot switch and remote
keypad (optional accessories)
See "D" in the Appendix.
The foot switch and the remote keypad are
available as optional accessories. For more
information see "Items supplied", page 16.
Connecting the foot switch
The connecting cable fixed to the foot switch has an RJ-45
plug for connection to the RJ-45 jack on the left side of the
unit.
Connect the RJ-45 plug of the foot switch to the RJ-45
jack provided on the unit.
Connect the remote keypad
The remote keypad is connected to the RJ-45 jack on the
left side of the unit by using a cable with RJ-45 plugs on
both ends.
Plug a cable with RJ-45 plugs into the RJ-45 jacks on the
unit and on the remote keypad.
Connecting foot switch and remote keypad
simultaneously
The foot switch and the remote keypad can be
used individually or in combination.
The foot switch and the remote keypad can be
connected simultaneously using an RJ-45 splitter
that is plugged into the RJ-45 jack on the left
side of the unit. RJ-45 splitters are available from
most retail electronics stores.
RJ-45 plug: Pin layout
See "M" in the Appendix.
4.8 Wiring of switching inputs and outputs
The functions are based on the formulas and
values stored by qualified personnel.
The wiring of the switching inputs and outputs depends
on the customer's peripherals (see manufacturer's
documentation).
Personnel requirement
Depending on the peripherals to be connected,
the connection work may need to be carried out
by an electrical specialist.
Example: SELV exceeded.
Relay connection
The contacts of a single-pole, double-throw dry-contact
relay are accessible on the product's rear panel for special
applications requiring low-power electrical switching. The
normally open and normally closed contacts of the relay are
available for use in low-current, low-voltage applications.
For more information on the relay connection, see
"Specifications", page 20.
Relay connector:
Pin layout
See "N" in the Appendix.
Data I/O connection
The I/O interface enables the digital readout unit to
communicate with the peripherals through TTL inputs and
outputs. Signals from peripherals can be evaluated and
connected peripheral devices can be controlled.
For more information about the I/O connection, see
"Specifications", page 20.
