PowerWizard 1.1 & 2.1 Control Panel: Complete Guide | FG Wilson Generator
PowerWizard 1.1 & 2.1 Control Panel: Technical Overview
Everything you need to know about FG Wilson’s technical architecture — core digital configurations, SPN/FMI alarm infrastructure, and precise component troubleshooting pathways.
The PowerWizard 1.1 and its advanced multichannel variant, the PowerWizard 2.1, serve as the standard digital control infrastructure across the global fleet of FG Wilson generating sets.
Mastering its integrated multi-layered button layout and specific diagnostic alarm logic determines the difference between a simple software reset and hours of highly expensive site downtime.
Technical Specifications At a Glance
| Variants | PowerWizard 1.1 · 1.1+ · 2.1 |
| Datalink Network | J1939 CAN Bus Link |
| Digital Inputs | 4 Channels (1.1) / 6 Channels (2.1) |
| Relay Outputs | 6 (1.1) / 8 Relay Contacts (2.1) |
| Core Modes | STOP · RUN · AUTO Status |
1. Control Panel Layout & User Interface
The control facade is systematically grouped into four logical operational zones:
AC Overview Key
Instantly redirects the screen matrix to AC metrics: line voltage, load current, and network frequency.
Engine Overview Key
Direct path to critical mechanical values including oil pressure, coolant temperature, and run hours.
Event Log Key
Opens the firmware tracking log to view active engine warnings and historical shutdown fault codes.
Lamp Test Key
Depress and hold to flush current to all LED indicators, instantly validating display pixels and safety diodes.
LED Alarm Indicator Meanings:
| LED Type | Flash Pattern | System Priority Level & Meaning |
|---|---|---|
| 🟡 Amber Yellow | Flashing | An unacknowledged warning is active. Diagnostics required. |
| 🟡 Amber Yellow | Solid Steady | Warning acknowledged; the triggering mechanical condition remains active. |
| 🔴 Alarm Red | Flashing | Critical unacknowledged SHUTDOWN event. Generator dropped load. |
| 🔴 Alarm Red | Solid Steady | Shutdown acknowledged. The engine remains locked out until fixed. |
2. Core Operating Modes Detailed
STOP Mode
The engine is powered down. Active errors can only be reset from this mode. The automatic remote sequence is completely overridden.
RUN Mode
Initiates manual starting sequence. Triggers automated pre-heat timing alongside safety checks and starter motor disengagement parameters.
AUTO Mode
Puts the panel into standby monitor status. Upon receiving an external command from an ATS, it manages startup and load automatically.
3. Automated Engine Cranking & Start Sequence
Pre-Start Validation
Scans logs for active interlocks. Fires up glow plugs or internal thermostart systems if configured.
Crank Engagement
Energises fuel racks and starter relays. Tracks magnetic pickup speed sensors for starter disengagement.
Engine Warm-Up
Brings engine safely to rated RPM. Managed automatically on the 2.1 via configuration cycle timers.
Load Accept
Once electrical frequency and voltages are completely stable, it signals the main breaker to engage load.
4. Diagnostic Fault Infrastructure (SPN / FMI)
The system tracks failures around standard SAE J1939 protocol logic. The SPN identifies the component, while the FMI states the fault type:
SPN 100 + FMI 1 ── Low Engine Oil Pressure Sensor.
→ Action: Controller issues an immediate shutdown to save engine bearings.
The fault condition is live. The firmware prevents manual resets until the component issue is fixed.
The problem has resolved but remains latched in memory. Requires a manual reset command to restore operation.
The event has been successfully reset. Held in history log alongside run-hour metrics for compliance audits.
5. Technical Fault Reset & E-Stop Workflows
Standard Event Reset Routine
- Diagnose and fully fix the physical root cause of the error.
- Press the STOP key on the panel to enter configuration mode.
- Press Alarm Acknowledge (LED drops from flashing to steady).
- Navigate: MAIN MENU → VIEW → EVENT LOGS.
- Select the reporting ECM engine subsystem.
- Highlight log line; ensure state is Active (not Present).
- Press Enter to flash the “RESET” prompt on screen.
- Press Enter again to confirm the status clear.
⛔ Emergency Stop Recovery
Twist physical mushroom button clockwise to pop it out. Enter STOP mode, navigate to event log, ensure it shows Active, then apply the standard reset steps.
⚡ Quick-Reset Command
Press STOP, then press and hold Alarm Acknowledge for 3 seconds to clear all resettable non-present events simultaneously.
6. PowerWizard 1.1 vs. 2.1 Technical Matrix
| Hardware Capability | PowerWizard 1.1 | PowerWizard 2.1 |
|---|---|---|
| Programmable Digital Inputs | 4 Channels | 6 Channels |
| Relay Output Configurations | 6 × Type-A Relays | 8 (6 Type-A + 2 Type-C) |
| Program Cycle Timer (PCT Engine) | Not Supported | Fully Integrated |
| Chronological Log Timestamps | Run-Hours Only | Real-Time Clock |
| SCADA Modbus Network Mapping | Basic Pack | Extended Mapping |
| Remote PC Monitoring Support | Requires Add-on Module | Requires Add-on Module |
LCD Burn-In or Communication Failure?
Unresponsive buttons or persistent J1939 network dropouts usually point to micro-component breakdown. LCP stocks premium refurbished, load-tested replacement panels ready for drop-in fitment on your FG Wilson genset.
Frequently Asked Technical Questions
Can I force a code reset while a fault is Present?
No. Safety firmware blocks software clear commands until the underlying mechanical or sensor error has been physically resolved on the machine.
Are PowerWizard 1.0 and 1.1 panels interchangeable?
They share the same physical cutout footprint, but internal software mappings differ. Interchanging them requires database parameter edits via toolkits.
