The Pressac Wireless 2 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 conductors and there is more than 1A flowing in all three CT Clamps. If this is the case, clip the CT clamps around the conductors 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 underside of the product. The LED should briefly flash. The Pressac Sensing Wireless 2 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 Wireless 2 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 2 Channel CT Clamp.

To be able to measure the currents flowing within the cable, the Pressac Sensing 2 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 combined current lower than 1A is flowing, the Pressac Sensing 2 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):
