Figure 1: Samlex RC-300 Remote Control Front Panel
The image displays the front panel of the Samlex RC-300 remote control. It features an LCD screen for displaying various inverter parameters, a 'DISPLAY' button to cycle through readings, a power button, and three LED indicators for 'OVERLOAD' (red), 'OVER TEMP' (yellow), and 'POWER' (green). The screen can show Voltage (V), Current (A), Frequency (Hz), Power (W), Apparent Power (VA), and Power Factor (PF).
3.1 Components
- LCD Display: Shows AC Voltage, AC Current, Frequency, Power (Watts), Apparent Power (VA), and Power Factor.
- DISPLAY Button: Cycles through the various parameters on the LCD.
- Power Button: Controls the ON/OFF state of the connected inverter.
- OVERLOAD LED (Red): Illuminates when the inverter is in an overload condition.
- OVER TEMP LED (Yellow): Illuminates when the inverter is experiencing an over-temperature condition.
- POWER LED (Green): Illuminates when the inverter is powered on and operating normally.
- RJ-50 Cable: 25-foot (7.6m) cable for connecting the remote control to the inverter.
4. Setup and Installation
Follow these steps to properly connect your RC-300 remote control to your Samlex PST 3000 series inverter.
- Ensure Inverter is Off: Before connecting the remote control, ensure your Samlex PST 3000 series inverter is turned off and disconnected from all power sources (DC input and AC output).
- Locate Remote Port: Identify the remote control port on your Samlex PST 3000 series inverter. Refer to your inverter's manual for the exact location.
- Connect Cable: Insert one end of the provided RJ-50 (10P10C) cable into the remote control port on the inverter.
- Connect Remote Control: Insert the other end of the RJ-50 cable into the corresponding port on the back of the RC-300 remote control.
- Secure Connection: Ensure both connections are secure.
- Power On Inverter: Reconnect power to your inverter and turn it on. The RC-300 remote control should now be operational.
5. Operating Instructions
Once connected, the RC-300 allows you to monitor and control your inverter remotely.
5.1 Powering the Inverter On/Off
- To turn the inverter ON, press and hold the Power Button (⏻) on the RC-300 for approximately 3 seconds. The green POWER LED will illuminate.
- To turn the inverter OFF, press and hold the Power Button (⏻) again for approximately 3 seconds. The green POWER LED will turn off.
5.2 Monitoring Inverter Parameters
The LCD display on the RC-300 shows various operational parameters of the inverter.
- Press the DISPLAY button to cycle through the available readings. Each press will advance to the next parameter.
- The display will show: AC Voltage (V) → Active AC Current (A) → Frequency (Hz) → Power (Watts) → Apparent Power (VA) → Power Factor (PF).
5.3 LED Indicators
- POWER (Green): Indicates the inverter is powered on and functioning.
- OVERLOAD (Red): Indicates the inverter is experiencing an overload condition. Reduce the load connected to the inverter immediately.
- OVER TEMP (Yellow): Indicates the inverter's internal temperature is too high. Ensure adequate ventilation around the inverter.
6. Maintenance
The Samlex RC-300 remote control requires minimal maintenance.
- Keep the unit clean and free from dust. Use a soft, dry cloth for cleaning.
