Service guide

2.0 Introduction

In smaller district heating networks ligthning can be a challenge for

the connected devices like ECL Comfort 296 / ECL 310 controllers.

If not protected, Modbus interfaces are subject for being burned in

case of lightning.

Based on several market inputs and analysis we identified a need for

information.

This has resulted in the present service guide which includes

recommendations for new installations.

The document is prepared in compliance with www.modbus.org

1. Each nodes in the "Modbus network" (central heating station,

repeater station or individual house) are highly recommended

to have "surge protector". It must be selected as per section 6

and installed as described in section 7.

2. Phoenix "PT 1X2+F-BE" (or similar products from another manu-

facturer, as per the surge protection requirement in section 6)

must be used instead of "PT 1X2-BE" in individual house installa-

tions. Refer section 8.

3. Recommendation on Modbus reference common signal con-

nection, shield connection, termination resistor connection may

be referred in section 5, 6, 7 and 8.
