6. REPAIR
IN CASE OF DIFFICULTY
In case of installation or programming difficulty, first check the programming. Some
problems occur due to improper setup or programming. Additionally, it is a good idea to
again go through the installation and adjustment procedures. If the unit continues to fail, call
the Zetron Model 15P Applications Department at (425) 820-6363. In case of malfunctions
that are not programming or installation related, contact the Zetron Model 15P Service
Department at the same number.
When calling Zetron for help, please have the serial number of the unit and/or the Zetron
order number (the order number is momentarily displayed when powered up). If an error
message is displayed by the unit following power up, please record this number as well.
If the call is made from the installation site by the installer or technician, the problem can
usually be solved over the phone.
The parts list and schematic for the encoder are included in this section to aid in the
installation or repair of the unit.
SELF-TEST
The built-in self-test, which is automatically run when the encoder is powered up, checks the
display by lighting all display segments and tests internal digital circuitry.
If an error occurs, then the test is halted and an error code is displayed in the front-panel
window.
