SmartGen HMC4000RM Remote Monitoring Controller

1 OVERVIEW

The HMC4000RM remote monitoring controller integrates digitization, intelligentization, and network technology for remote monitoring systems of single units to achieve remote start/stop functions. It features an LCD display and optional Chinese/English language interfaces, making it reliable and easy to use.

2 PERFORMANCE AND CHARACTERISTICS

Main features include:

• 132*64 LCD with backlit, optional Chinese/English interface display, and push-button operation.
• Hard-screen acrylic material protects the screen with excellent wear-resisting and scratch-resisting functions.
• Silicone panel and buttons provide great performance in high/low temperature environments.
• Connects to the host controller via RS485 port for remote start/stop control.
• Adjustable LCD brilliance level (5 levels) for convenience in different occasions.
• Waterproof security level IP65 due to a rubber seal between the controller enclosure and panel fascia.
• Uses metal fixing clips.
• Modular design with self-extinguishing ABS plastic enclosure and embedded installation for small size and compact structure with easy mounting.

6 CONTROLLER PANEL AND OPERATION

6.1 CONTROLLER PANEL

Fig.1 HMC4000RM Front Panel Description:

The front panel features an LCD display and several pushbuttons:

• Alarm Indicator: Indicates alarm status.
• Genset Status Indicator: Indicates the operational status of the genset.
• Stop Button: Red button labeled 'Stop' (Chinese: 停机).
• Start Button: Green button labeled 'Start' (Chinese: 起动).
• Dimmer + Button: Labeled 'Dimmer +' (Chinese: 亮度加) for increasing LCD brightness.
• Dimmer - Button: Labeled 'Dimmer -' (Chinese: 亮度减) for decreasing LCD brightness.
• Lamp Test Button: Labeled 'Lamp Test' (Chinese: 试灯).
• Set/Confirm Button: Used for setting and confirmation.
• Up/Increase Button: Arrow pointing up.
• Down/Decrease Button: Arrow pointing down.

Indicator Light Explanation:

• Alarm Indicators: Slowly flash for warning alarms; fast flash for shutdown alarms; off when no alarms.
• Status Indicators: Off when genset is standby; flash once per second during start up or shut down; always on during normal running.

6.2 REMOTE START/STOP OPERATION

6.2.1 ILLUSTRATION

By pressing a button on the host controller HMC4000, users can enter remote control mode to remotely control the HMC4000RM start/stop operation.

6.2.2 REMOTE START SEQUENCE

• When a remote start command is active, the “Start Delay” timer is initiated and its countdown is displayed on the LCD.
• When the start delay is over, the preheat relay energizes (if configured), and “preheat delay XX s” information is displayed on the LCD.
• After this delay, the Fuel Relay energizes, followed one second later by the Start Relay engagement. The genset is cranked for a pre-set time. If the genset fails to fire during this attempt, the fuel relay and start relay disengage for a pre-set rest period, initiating “crank rest time” before the next crank attempt.
• If the start sequence continues beyond the set number of attempts, it terminates, and a “Fail to Start” fault alarm is displayed on the LCD.
• Upon a successful crank attempt, the “Safety On” timer activates. Once this delay expires, the “start idle” delay is initiated (if configured).
• After the start idle, the controller enters the “Warning Up” delay (if configured).
• After the “Warning Up” delay expires, the generator enters Normal Running status directly.

6.2.3 REMOTE STOP SEQUENCE

• When a remote stop command is active, the controller starts a high-speed “Cooling” delay (if configured).
• Once the “Cooling” delay expires, “Stop Idle” is initiated. During “Stop Idle” Delay (if configured), the idle relay is energized.
• Once “Stop Idle” expires, the “ETS Solenoid Hold” begins, determining if the stop is complete. The ETS relay energizes while the fuel relay de-energizes.
• Once “ETS Solenoid Hold” expires, the “Wait for Stop Delay” begins, and complete stop is detected automatically.
• The generator enters standby mode after its complete stop. Otherwise, a “fail to stop” alarm is initiated and displayed on the LCD. If the generator stops successfully after a “fail to stop” alarm, it enters standby status.

9 TYPICAL APPLICATION

Fig.3 HMC4000RM Typical Application Diagram Description: The diagram illustrates a typical application where the HMC4000RM controller is connected to a power supply (represented by a battery symbol with B+ and B- terminals) and a host controller (HMC4000MPU) via RS485 communication.

10 INSTALLATION

10.1 FIXING CLIPS

The controller features a panel built-in design and is fixed by clips during installation:

• Withdraw the fixing clip screw (turn anticlockwise) until it reaches the proper position.
• Pull the fixing clip backwards (towards the back of the module) ensuring two clips are inside their allotted slots.
• Turn the fixing clip screws clockwise until they are fixed on the panel.

NOTE: Care should be taken not to over-tighten the screws of the fixing clips.

10.2 OVERALL DIMENSIONS AND CUTOUT

Fig.4 Case Dimensions and Panel Cutout Description: The diagram shows the controller's external dimensions: 135mm width, 110mm height, and 44mm depth. The required panel cutout dimensions are 116mm width and 90mm height.
