Thyssen K200 Door Operator BG101-S20P4A – Silent, Speed-Optimized Motion for K200 Cars | Nanjing Zhuye Elevator Parts
First impressions start with the door. The Thyssen BG101-S20P4A operator delivers the speed and silence K200 cars are famous for—0.4 m/s opening, 0.35 m/s closing, adaptive torque and ≤ 55 dB(A) at 1 m. Built into Thyssen K200, K200-MO and modernisation packages, it mates with the K200-MCB control board to open 900 mm panels in < 2.2 s while keeping closing force under 150 N. When belts slip or the encoder drifts, passengers feel a shudder or nudge-loop. Nanjing Zhuye Elevator Parts keeps genuine BG101-S20P4A operators—motor, belt, encoder and mounting template—in stock for next-day despatch worldwide, helping you restore premium door motion without costly OEM delays.

Thyssen K200, K200-MO, K200-MRL side-opening passenger elevators
-
Modernisation packages replacing older K100 or relay-logic operators
-
Any door height 2 000-2 600 mm, sill width 400-1 100 mm, 1:1 or 2:1 belt arrangement
Installation method – 30-minute field swap
-
Place lift on inspection mode; open doors manually; switch OFF local breaker; lock & tag.
-
Remove operator cover; release belt tensioner; photograph encoder and power connectors.
-
Unbolt old operator (4 × M8); lower onto pad to avoid encoder damage.
-
Mount BG101-S20P4A template; torque M8 bolts to 18 Nm.
-
Install poly-V belt; tension to 2 % of length (deflection 6 mm at 200 mm span).
-
Connect 24-48 V DC (red +, black −), CAN-FD (H/L), encoder 8-pin, safety-edge 24 V.
-
Power up; green “RDY” LED blinks; board auto-detects motor direction and encoder type in 5 s.
-
Launch Thyssen K200 Tool (TK2-12) on laptop; auto-learn runs full stroke twice, records inertia, friction, backlash.
-
Fine-tune curves: open speed 0.4 m/s, close speed 0.35 m/s, nudging torque 45 %, brake delay 0.2 s.
-
Execute 50 continuous cycles; verify temperature < 50 °C on motor flange and no fault codes.
-
Apply torque-stripe paint; log serial number and date in maintenance book.
Replacement cycle & preventive maintenance Thyssen bulletin SB-K200-DO-2024-04 recommends:
-
Visual inspection every 6 months: check belt wear, encoder alignment, loose bolts.
-
Belt test: replace poly-V when cracks > 2 mm or ribs missing, or when deflection > 3 %.
-
Encoder test: oscilloscope trace must show clean 0-5 V square wave; replace motor if jitter > 5 %.
-
Replace entire operator every 12 years or 3 million cycles, whichever comes first.
-
Immediate replacement if:
– motor stalls with < 0.2 Nm torque (magnet demagnetisation),
– encoder Hall error persists after cable swap,
– temperature > 70 °C on flange (fan failure),
– belt slips after re-tension (pulley worn).
Pro tip: 60 % of premature failures are traced to over-tensioned belts—keep deflection at 2 % of span.
Maintenance tips from Nanjing Zhuye Elevator Parts
-
Always use the supplied key and torque driver; loose keys ovalise the shaft and destroy the encoder disk.
-
Never pressure-wash the operator; water enters the encoder and locks the Hall sensors.
-
Keep a spare BG101-S20P4A in every service van; at 2.8 kg it costs less than one callback night.
-
After heavy cleaning, run 5 cycles to redistribute grease inside bearings and verify encoder count.
-
Order the “K200 Door Kit” (operator + belt + encoder cable + torque tool) from Nanjing Zhuye Elevator Parts to eliminate parts hunting and ensure matched components.
