GE DS3820LT4A1C1A Speedtronic Mark IV Load Trak IV Control Panel
The GE DS3820LT4A1C1A, also cataloged as the DS3820LT4A Control Panel, operates as a dedicated hardware component for motor load monitoring and local operator control within Speedtronic Mark IV systems. The panel manages analog temperature and current sensing inputs to drive local display feedback and execute PID-based load regulation algorithms.

Backplane Bus Communication Velocity Licences and Deterministic Execution
The DS3820LT4A1C1A interfaces with Mark IV control racks via isolated RS-232 and RS-485 serial communication links, transferring local setpoint entries and fault trip parameters without impacting backplane bus communication velocity across central processor racks. Real-time conversion of 4 differential analog input channels (0-20 mA / 0-10 V) and execution of PID load control algorithms occur locally within the controller assembly. This hardware distribution ensures continuous motor temperature and current protection even during transient network updates on primary system buses.
Frequently Asked Questions
Q: How does the DS3820LT4A1C1A process local fault trip triggers?
A: The panel continuously monitors incoming temperature and current loop signals against programmed threshold values, energizing its onboard digital relay outputs to initiate alarm contacts without software intervention.
Q: What power options are supported for field installation?
A: The module supports field-selectable operating power inputs, accepting either +24 VDC at 500 mA or 120 VAC line power.
Q: Can front-panel configuration parameters be adjusted while the unit is mounted?
A: Yes, operators execute real-time setpoint adjustments and view operational diagnostic logs directly via the integrated 5.7 in LCD display and 20-button tactile keypad.
Field Installation Guidelines
Mount the control panel into the cabinet door cut-out using the perimeter sealing gasket to maintain the IP54 front panel ingress rating. Secure all panel mounting clamps evenly around the frame to prevent mechanical stress on the LCD membrane.
Connect incoming RS-232 or RS-485 serial communication lines using shielded twisted-pair conductors, terminating shield drain wires at the main cabinet earth bus bar. Route 0-20 mA temperature/current sensor wiring in grounded conduit separate from AC power cables. Confirm that the input voltage select jumpers match the supply power configuration (24 VDC or 120 VAC) before energizing the cabinet line.
