Operates standalone, via PC software (3SModbus/Sensistant), or SenteraWeb.
PT500 temperature probe input, potentiometers for 15-35 °C setpoint and min speed.
Internal trimmer for max speed, hysteresis, and proportional range.
Reliable RABS V0 grey (RAL7035) enclosure.
230 VAC supply; adjustable Vmin (80-160 VAC) and Vmax (170-230 VAC).
Additional specifications and description
How Does the GTE-1-60-DM Provide Versatile Temperature-Based Fan Control?
If you need versatile fan speed control in your glasshouse, this is what you need. This device is intended for monophasic voltage controllable motors and control is based on the measured temperature. What makes it perfect for your contemporary hothouse is the fact that it features Modbus RTU. This means you can control the environment parameters remotely or automatically based on the settings you have applied. When the measured temperature is lower than the temperature setpoint, the fan runs at low speed. When the selected temperature is exceeded, the fan accelerates. The higher the measured temperature, the higher the fan speed.
What Are the Operation and Control Modes of the GTE Controller?
The controller can be used both as a stand-alone unit or in conjunction with a computer and operated by Sentera’s 3SModbus software or the Sensistant configurator. When used stand-alone, its jumpers need to be set to the desired values. This means the device is controlled manually.
When used in Modbus mode, its parameters are set via Modbus RTU. This means the device is controlled remotely via a PC, so there is no need to set the jumpers, i.e. they can remain in their factory set positions.
The device also features a further option – you can connect it to SenteraWeb and control the GTE via the Internet.
How Can Controller Settings Be Adjusted and Monitored?
All settings of this fan speed controller can be adjusted and monitored via Modbus RTU communication. The output voltage can be set locally via the built-in potentiometer or remotely via Modbus RTU communication. All you need to do is download our free 3SM Software from our website and you get the motor control type you wish – manual or digital, i.e. local or remote!
What Type of Temperature Probe is Required for the Controller?
A PT500 temperature probe needs to be connected to the controller in order to measure the temperature in the relevant area. Based on the measured temperature the controller works toward reaching the setpoint selected via the potentiometer on the enclosure or via Modbus (bear in mind that Modbus mode overrides manual control).
Can Multiple Motors Be Connected to This Controller?
You can connect several motors to the controller as long as the current limit of 6 A is not exceeded. In this case all of them will run at the same speed.
What is the Purpose and Function of the Unregulated Output?
The GTE features an unregulated output, called so because it is either ON (230 Volt) or OFF (0 Volt). If the supply voltage is connected to L and N, the unregulated output is active while the motor is in operation. You can use this output to control external devices (2 A maximum current), for example a run-indicator or a damper, etc. This means that while the fan is working, the damper will be open or the run indicator will be on. When its stops, the damper will close and the indicator will be off.
What Are the Safety and Durability Features of the Controller's Enclosure?
This controller is the result of many years of experience in greenhouse air extraction combined with innovative electronics technology. To make the device reliable and safe we manufacture the enclosures in our own factory. This enclosure is made of high-quality R-ABS, V plastic. This material is flame retardant, very though and offers good protection against impacts. Its ingress protection class is IP54 against dust, dirt and water.
