Installation Example

The following figure shows an example of installing devices for temperature measurement in the

industrial control panel. Accura 2500 and Accura 2550TEMP modules are installed at the front of the

industrial control panel, and multiple Accura TSEN/THSEN* devices are installed inside the industrial

control panel. Up to 6 Accura TSEN/THSEN devices can be connected to the Accura 2550TEMP module

with the daisy-chain method. The Accura 2550TEMP module has 1 DI(Digital Input) channel and 1

DO(Digital Output) channel, allowing for the installation of the reset switch and warning light for events.

* Accura TSEN and THSEN are also referred as temperature/humidity sensing devices in this document.

Step 2: Installing Accura TSEN/THSEN

Accura TSEN/THSEN can be installed by using either the panel mounting or DIN rail mounting method.

Accura TSEN is installed for temperature measurement in the industrial control panel, while Accura THSEN

is installed for temperature and humidity measurements in the industrial control panel.

Panel Mounting

① Insert the mounting wings into Accura TSEN/THSEN.

② Fit the screw holes of the mounting wings into the mounting holes on the panel.

③ Fix Accura TSEN/THSEN onto the panel using the screws.

Fig 1.12

Mounting Accura TSEN/THSEN on the Panel

DIN Rail Mounting

① Place the bottom portion of the Accura TSEN/THSEN device onto one side of the DIN rail.

② Once one side of the device is latched on the rail, push the other side towards the panel so

that Accura TSEN/THSEN can get snapped onto both ends of the DIN rail flanges.

Accura 2550TEMP Operation/Setup

Accura 2550TEMP, the temperature measuring module is installed at the front of the industrial control

panel, allowing users to manage the overall temperature of the industrial control panel. It measures the

external temperature of the industrial control panel with its built-in temperature sensor located at the

front bottom of the module. It can be connected to up to 6 Accura TSEN/THSEN devices in a daisy chain

and collects the temperature and humidity data measured at multiple locations in the industrial control

panel from Accura TSEN/THSEN.

Through Accura 2550TEMP, users can check the temperature data measured by the module and the

temperature/humidity data collected from Accura TSEN/THSEN and set up events related to temperature.

Event notifications are generated according to the settings, and users can check detailed event data.

Users can reset notification settings for external temperature events only on Accura 2550TEMP module.

However, for the events detected by the Accura TSEN/THSEN device, users can reset event notifications

only with the RESET button on the device.

Connected to Accura 2500M using an internal communication cable, Accura 2550TEMP module

sends/receives data to/from Accura 2500M. It receives control power from Accura 2500M via the internal

communication cable. For details about installing Accura 2550TEMP and connecting it to Accura 2500M

and Accura TSEN/THSEN, refer to 「Chapter 1 Installation & Wiring > Step 2: Installing Accura 2550TEMP」.
