SECTION 7 : MAINTENANCE
7.1. GENERAL
Digital technology is a reliable alternative to analogue systems and it usually does not require
maintenance intense tasks. The reliability of the Digital Thyromat Controller ensures that preventative
and corrective maintenance is minimal. Maintenance is simplified and equipment down times greatly
reduced due to the modular design of the THYROMAT. Added features such as Monitoring / Fault
History assists the user in accurately identifying failures / faulty components within a short period of time
with confidence.
It is recommended that the user retains a complete THYROMAT control unit to be used as spares. The
simplistic design of the unit and the mounting procedures does not require specialised knowledge. The
ease at which faulty components / units can be replaced will greatly reduce equipment down times.
A second option would be to keep a spare set of modules for the THYROMAT. The identification and
replacement of faulty cards require a suitably qualified person to carry out the task. The cards have
voltage sensitive devices that can be damaged if handled incorrectly.
7.2
PREVENTATIVE MAINTENANCE
Because of the design of the THYROMAT there are no preventative maintenance tasks required.
Preventative maintenance may be required for the associated equipment, that depends on the various
associated equipment and the applicable manufacturer’s specifications.
7.2.1
Brakes
CAUTION
NEVER ASSUME THAT THE MECHANICAL
BRAKE IS CORRECTLY SET. INCORRECT
SETTINGS CAN LEAD TO FAILURE AND CAN
CAUSE DAMAGE TO PROPERTY AND FATAL
INJURIES.
One item that is critical to the safety and operation of the THYROMAT is the serviceability of the
mechanical brake.
It is important that the mechanical brake is set in such a manner that it will stop a full load without
motor assistance.
The mechanical brake must be checked at regular intervals.
