The Multi Point Controller (MPC) firmware version 2.03 has some great improvements. We have added the ability to configure the behaviour of digital outputs on the MPC under fault conditions such as comms failure. The outputs can now be configured to be turned off (RELEASE) or held in their current state (HOLD) in the event…

A recent investigation demonstrated the flexibility and power of the XL4 Plus RTU comms options. The new rural water scheme is planned for a remote part of NZ. The aim is to add up to ten new telemetry sites over two separate zones. Hydraulically, the water scheme interconnection is relatively straightforward with a maximum of…

The 3G networks are closing soon in New Zealand. One NZ (previously Vodafone NZ) plans to switch off in 2024, and Spark is likely to be similar. We appreciate this is not “new news” as some 3G networks have already been switched off overseas.However, this does not just impact old cell phones. We encourage you all…

We were approached to provide a control solution for remote latching solenoids over a distance of 1200m. Latching solenoids are commonly used in the irrigation market as they are very low power. Latching solenoids require a special driver circuit which controls the polarity of the switching signals. Latching solenoid control can easily be achieved with…

Cellular connectivity and internet availability in rural NZ has been challenging for a long time. Black spots, call drop outs and being unable to use mobile technology in every location, has always been a problem. However, the government’s “statement of intent for improving digital connectivity ” has been recently announced by MBIE. Needless to say,…

We have been approached by several DATRAN SCADA users for advice on server replacement and migration projects. QTech has now produced detailed technical resources to assist all system administrators and IT staff looking at performing DATRAN server and SQL database migrations. Importantly, please get in touch with us before starting the project as there are…

Backing gates are slow moving motorised barriers that control dairy herd movement into the milking platform. The motor drive units used are often water powered devices. Using water removes the need for long cable runs and the water also helps with the yard clean up. A recent enquiry needed to add remote valve control to…

Our customer wanted to send reservoir water levels out as a text message every hour. Whilst the reservoir is already part of a DATRAN telemetry system, an additional stand alone system was required. It was to be funded separately and used to notify different users. Local community stake holders need the reservoir level information as…

QTech SMS Controllers perform controller to controller texting, allowing a mini cellular control network to be created. We were approached by a large New Zealand dairy cooperative for a cellular monitoring solution. The recent cyclone had impacted the existing control system – the cellular network being used was damaged and became unavailable. An alternate and…

QTech cellular controllers are used to monitor a client’s cold room. The cold room is used to store high value seed potatoes. Seed potatoes need to be kept cold and dry for long periods each year, to ensure they are ready for next season’s crop. Power outages are becoming more common, so a way to…
