Safety and EMC
Safety is paramount at all times.
The Controller has a number of built in safety features; password protection for the Product Parameters, a
different password for Commissioning, the MAN/AUTO/OFF keys may be disabled, the Controller may
only be changed to LOW tension when the tension is OFF and all SET UP keys are disabled when MAN
or AUTO are selected. The KEY LED will confirm if any key is pressed. The Controller will not accept an
invalid input value which is outside the limits of operation; if an invalid input is attempted the Controller will
revert to the previous valid input. The Controller has been designed to meet UL and CSA requirements.
The Controller is self certified as compliant with the EC Low Voltage Directive 73/23 and is CE marked.
The Controller is self certified as compliant with the EC EMC Directive 89/336. However the EMC
performance will depend on the installation and environment and CMC Inc can give no guarantee that the
installation will be free of problems. The Controller must be installed using best EMC practice and in
particular the earth connection must provide a good EMC path to earth.
Additional Information
The CCFL (cold cathode fluorescent light) has a minimum expected life of 20,000 hours.
The non-volatile memory is battery backed. The battery has an expected life of one year without a
recharge. The battery will recharge when the Controller is powered.
During power up the Controller may output a signal which may cause the machine to move if the
controlled drive is powered and enabled.
External tension set point input
This is an analog signal of 0 to +10V DC, for Master - Slave applications. The input resistance is 100K S.
The EXT SET POINT must be enabled in Machine Parameters to use this feature.
Tension set point output
This is an analog signal of 0 to +10V DC at 2mA maximum, for Master - Slave applications.
Adjusting the screen contrast
There are two unmarked keys, one below the CONFIRM key the other below the TENSION OFF key.
Press both together and release, the KEY LED will flicker. Whilst flickering press one or the other
unmarked key as required to adjust the screen contrast, release and allow the flickering to terminate.
