The Pressac Sensing 3 Channel CT Clamp needs to be commissioned before use. There are 2 ways in which the unit can be commissioned.

  1. Self-powered learn
    As the unit is 100% energy harvesting, it can only perform a self-powered learn if it is clipped around a conductor and the minimum required current is flowing. (See below table)

3 Channel CT Clamp Versions

200A Version

868MHz 902MHz 928MHz

2A Flowing

600A Version

868MHz 902MHz 928MHz

2A Flowing


Clip the CT clamp around the conductor and wait for a period of 30 seconds. With a suitable tool (sharp, non-metallic, non-conductive element), depress the learn button which is on the sender unit. The LED should briefly flash. The Pressac Sensing 3 Channel CT Clamp is now commissioned.

  1. Manual registration.
    Alternatively, the unit can be commissioned onto your EnOcean network manually. To do this you will need the unique EnOcean ID of the Pressac Sensing 3 Channel CT Clamp and also it’s EnOcean Equipment Profile. The EnOcean ID and the EEP are printed on the product label on the Pressac Sensing 3 Channel CT Clamp.

To be able to measure the currents flowing within the cable, the Pressac Sensing 3 Channel CT Clamp must be correctly clipped around the cable, ensuring that the ferrite cores within the clamp reliably and consistently touch each other. In permanent installations, the unit can be cable tied to the conductor for added security.

Once installed and commissioned, the value of electric current is transmitted every 30 seconds. If a current lower than the minimum current required (See above table) is flowing, the Pressac Sensing 3 Channel CT Clamp will not report any information or transmit any EnOcean telegrams.

The product uses an EnOcean STM300 Module for transmitting the data wirelessly. It supports the following EEPs (EnOcean Equipment Profiles):
