MAINTANENCE :
SYTCO Fail Safe Brakes are almost maintenance free. For this periodicity depends
on application to application, operating frequency, system inertia to be stopped etc. air gap can be
adjusted by rotating adjustable Hollow Bushes to reduce air gap. Rotate all bushes anti-clockwise
and check from all sides by filler gauge and vice-versa.

TYPICAL CASES OF WRONG FITMENT
Typical case of uneven air gap in brake disc: This should be noticed and avoided during
preventive maintenance.
Typical case of stator resting bolt head, which will restrict the stator lateral movement of brake
disc: This should be noticed and avoided during preventive maintenance.
Typical case of stator fitting, the half-moon slot is to clear the bolt head, brake housing fitment
wrong, which will obstruct the stator lateral movement of brake disc: This should be noticed
and avoided during preventive maintenance.
TYPICAL CASES OF WRONG WIRING
The RYB colour code of connecting cables to be maintained and wiring connections to be
followed accordingly. The supply voltage is 415+/-10% for all AC brakes. The power supply
fluctuations will have effect on brake coil first than motor as coil are more sensitive than motor
windings.
