The QTech SMS Lite is used to remotely start and monitor your generator via text messages over the 4G cellular networks.
We have been involved with a generator remote start project for the popular Kubota GL600D-AU-B genset fitted with the DSE 4520 digital control panel.
The generator remote start ability was of crucial importance for the customer. Milne Bros, the local distributor was contacted for assistance. They evaluated the compatibility and interface wiring prior to the customer purchasing the genset.
DATRAN Australia and QTech in NZ were involved in the discussion to ensure the customer could achieve remote starting using text messages.
The Kubota GL600D-AU-B genset has many great features. It was selected as it has quiet running, efficient fuel use and an auto change over for when the mains power drops out.
The SMS Lite interfaces to the DSE 4520 control panel – Input A, pin 14 is wired to the SMS Lite output relay RLY1. Sending a text message to the SMS Lite closes the relay and activates pin 14 (connects it to ground) remotely starting the genset.
The SMS Lite’s low power relay outputs are ideal for this type of electrical switching.
More details on the DSE4250 control panel, including the wiring diagram and I/O configuration options is available here.
The genset also has multiple outputs that can be monitored by the SMS Lite and used to send text messages to notify you. Typical example would be the genset has started as the mains has dropped out.

There are many different types of generators available, but you need to ensure that yours has a suitable electrical interface for remote starting.
Remote start kits provide the electrical interface to the necessary start button, kill switch etc. They can be a factory fitted option, pat of the control panel or an aftermarket accessory. Please contact your provider with this note.
SMS Lite – Relay Output Options
The SMS Lite relay outputs can be turned on, off, pulsed for 1 second or pulsed for a configurable time. This is useful as the generator’s remote start interface may need an activation signal for several seconds before operating. Some generators also have separate start and stop inputs.
SMS Lite – Input Switch Debouncing
Input switch debouncing is also a good idea and will prevent false alarms and help reduce the quantity of SMS/texts sent. Debouncing is configurable, it’s a global setting so applies to all four inputs.
Low Voltage Warning
The SMS Lite automatically sends you a text message if the supply voltage drops to 10.5V DC. When voltage increases to 11.5V DC a confirmation text will also be sent.
Fuses and Relays
Remember to install suitable fuses in the interface wiring.
A DC supply isolator switch for the SMS Lite should be installed if the device will be unused for extended periods or powered from the generator’s starter battery.
We recommend installing interface relays on the output side of the SMS Lite controller. This assists future serviceability and allows high current/voltage operation. The SMS Lite relays are rated at a maximum of 2A at 32V DC only.
Antenna Selection and Mounting
Please remember to mount vertically and away from conductive poles etc.
The 4G SMS Lite is the first choice for Generator Control using SMS.
