Section 7: Maintenance
7.1
Maintenance Schedule
TEC2 Series has been designed and manufactured to provide years of trouble free service.
Minimal maintenance is required.
It is not unusual to experience some minor grease weeping around seals during periods
of long storage or inactivity. This is simply a separation of the oil in the compound and
is not detrimental to the actuator operation. Once operation has begun, this situation
should disappear.
7.2
Lubrication
Normal operation may not require lubricant during the life of the actuator. The basic
lubricants used are multi-purpose extreme pressure specially formulated having a
molybdenum disulfide additive. For specific information, request Bettis Technical Sheet
Bettis–025.
7.3
Pressure Relief
During actuator operation, a small pressure builds up as a result of the gear temperature
increase combining with the varied outdoor temperature.
1.
After actuator has been located in the field and valve position has been
determined, remove 1/2 NPT plug from the highest 1/2 NPT vent location on
the gearbox.
2.
Replace with Relief Vent Fitting Part No. 83385. See the Bettis outline drawing
supplied with the order submittal package for possible vent locations.
NOTE:
Model 500 will not have a pressure relief fitting.
7.4
Fuse Replacement
Two transformer primary fuses are located in the Separate Terminal Compartment
(STC). To check or replace fuses, remove fuse cover by loosening the two Torx screws
and slip cover out from underneath screws. Replace fuse only with 600V, 2A fuse,
Bussmann TDC 600V 2A, BETTIS P/N 7019900425. Replace fuse cover and lightly
tighten screws. Do not over-tighten.
