Transducer Instruction Manual
Range:
LETIX
Type:
L-ANV-0-0-R-AC
Revision:
V1.0
3.
Supply Voltage
The LETIX is available in two power supply options, which are specified and fitted by CMC Controls
before despatch according to the clients’ needs.
This unit is fitted with an AC mains supply 110-230V universal. This has a RED main connector.
The supply
MUST
be via a 400 mA Anti surge fuse, or similar, with a local MCB or isolator.
NOTE
This unit is
not
fitted with a safety earth terminal. The protective Earth supply of the AC Mains and
the screens of the transducers, and any other cable, should be bonded to earth locally with short leads.

Calibration
4.1
Indicator
This is usually pre-set by CMC to the clients needs before despatch, but final calibration will always need
to be done on site, with the correct tension, wrap angle, roller, and transducers according to their
application.
To calibrate the LETIX indicator correctly a spring balance (or weights) to provide the required tension
force and some flat strapping or similar to simulate the web will be needed.
Connect the transducers correctly, and apply power to the unit. After a few seconds, it will go through the
start-up routine. It is a good idea to leave the power on for 10-15 minutes to allow the transducers to
settle.
IMPORTANT
Before calibration, ensure that the dipswitches at the rear of the unit are set to the UP
position. After calibration, set them to the
DOWN
position. This will stop the machine operator from
altering the settings and prevent re-calibration of the indicator.
