Maintenance
7.1. Maintenance Schedule
EIM TEC 2000 Series Actuators have 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
EIM Technical Sheet EIM–
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 ½ NPT plug from the highest ½ NPT vent location on the gearbox.
2. Replace with Relief Vent Fitting Part No. 83385. See EIM Outline Drawing No . XXX for
possible vent locations
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 form underneath screws. Replace fuse only with 600V, 2A fuse, Bussmann TDC 600V
2A, EIM P/N 7019900425. Replace fuse cover and snug down screws. Do not over tighten.
