Ramset RAM 100 DC Slide Gate Operator Replacement Parts

Genuine Ramset replacement parts for the RAM 100 DC (DC RAM 100s) slide gate operator — the 24 VDC brushless, battery-backup version of the RAM 100 gate opener. Use the diagram and the tables below to identify your part, then click any part number to order. The RAM 100 DC shares its chassis and mechanical layout with the RAM 100 AC, so most wear parts are the same; the motor, control boards, transformer and battery hardware are DC-specific.

About this diagram: Ramset has not yet published a DC exploded view, so the drawing above is the factory RAM 100 parts diagram. The RAM 100 DC uses the same layout, and the Ref numbers in the table match the callouts on this drawing. DC-only electrical parts (battery, DC driver board, bridge rectifier) are not shown and are marked —. Callouts on the drawing that are not listed below are AC-only parts — find those on the RAM 100 (AC) parts page.

Common Ramset RAM 100 DC Faults and the Parts That Fix Them

Operator chirping or running on battery only

The DC Alert chirp means the operator has lost AC supply and is running down its batteries. Check the incoming circuit and the rocker switches (800-60-10) first, then the transformer (800-60-07) and the bridge rectifier (800-60-35) that feed the charging circuit.

Dead after a power outage

If the gate opener will not run once AC power is restored, the batteries (800-70-00) have usually been discharged past recovery — replace them as a pair. If fresh batteries will not hold a charge, test the charging supply (transformer and rectifier above).

Boards power up but the motor will not run

Check the clutch release (800-75-21) has not been left disengaged after manual operation — the cheapest fix on this list. Otherwise test the DC driver board (800-65-05) before the brushless motor (800-04-04); the driver fails more often than the motor.

Gate overruns its open or close point

Worn limit components let the operator lose track of gate position. Inspect the limit chain (800-52-27) and limit switches (800-20-00), then the limit shaft assembly (800-75-72) if the shaft wobbles or the nuts no longer track.

No response to remotes or keypads

Accessories wire to the radio receiver terminal (800-64-50). If a known-good receiver and terminal still get no response, the logic board (800-65-01) is the next suspect.
