OVERVIEW

HMC4000RM remote monitoring controller integrates digitisation, internationalisation and network technology which are used for remote monitoring system of single unit to achieve remote start/stop functions. It fit with LCD display, and optional Chinese/English languages interface. It is reliable and easy to use.

PERFORMANCE AND CHARACTERISTICS

Main features are as follows:

132*64 LCD with backbit, optional Chinese/English interface display, and push-button operation;
Hard-screen acrylic material been used to protect screen with great wear-resisting and scratch-resisting functions;
Silicone panel and buttons with great performance to work in high/low temperature ambient;
Connect to host controller via RS485 port to achieve remote start/stop control in remote control mode;
With LCD brilliance level (5 levels) adjusting button, it is convenient to use in different occasion;
Waterproof security level IP65 due to rubber seal installed between the controller enclosure and panel fascia.
Metal fixing clips are used;
Modular design, self extinguishing ABS plastic enclosure and embedded installation way; small size and compact structure with easy mounting.

CONTROLLER PANEL AND OPERATION

**CONTROLLER PANEL

Fig.1 HMC4000RM Front Panel**

NOTE : Part of indicator lights illustration:
Alarm Indicators: slowly flash when warning alarms occurred; fast flash when shutdown alarms occurred; light is off when there are no alarms.
Status Indicators: Light is off when gen set is standby; flash once per second during start up or shut down; always on when normal running.

REMOTE START/STOP OPERATION

ILLUSTRATION

Press of the host controller HMC4000 to enter into remote control mode, after remote control mode is active, users can remotely control HMC4000RM start/stop operation.

REMOTE START SEQUENCE

When remote start command is active, “Start Delay” timer is initiated;
“Start Delay” countdown will be displayed on LCD;
When start delay is over, preheat relay energizes (if configured), “preheat delay XX s” information will be displayed on LCD;
After the above delay, the Fuel Relay is energised, and then one second later, the Start Relay is engaged. Genset is cranked for a pre-set time. If genset fails to fire during this cranking attempt then the fuel relay and start relay are disengaged for the pre-set rest period; “crank rest time” begins and wait for the next crank attempt.
Should this start sequence continue beyond the set number of attempts, the start sequence will be terminated, and Fail to Start fault alarm will be displayed on the alarm page of LCD.
In case of successful crank attempt, the “Safety On” timer is activated. As soon as this delay is over, “start idle” delay is initiated (if configured).
After the start idle, controller enters into hi-speed “Warning Up” delay (if configured).
After “Warning Up” delay expired, the generator will enter into Normal Running status directly.

REMOTE STOP SEQUENCE

When the remote stop command is active, controller starts hi-speed “Cooling” delay (if configured).
Once this “Cooling” delay has expired, the “Stop Idle” is initiated. During “Stop Idle” Delay (if configured), idle relay is energised.
Once this “Stop Idle” has expired, the “ETS Solenoid Hold” begins, and whether or not stop completely will be judged automatically. ETS relay is energized while fuel relay is de-energized.
Once this “ETS Solenoid Hold” has expired, the “Wait for Stop Delay” begins. Complete stop is detected automatically.
Generator is placed into its standby mode after its complete stop. Otherwise, fail to stop alarm is initiated and the corresponding alarm information is displayed on LCD (If generator is stop successfully after “fail to stop” alarm has initiated, engine will enter into standby status)

INSTALLATION

FIXING CLIPS

Controller is panel built-in design; it is fixed by clips when installed.
Withdraw the fixing clip screw (turn anticlockwise) until it reaches 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 fixing clips.
