Fig. 11 Example of a CIM 500 solution for Hydro Multi-E
model H and later. Pumps connected via built-in radio
communication (Grundfos Glowpan)
The example for Multi-E model H and later is identical for TPED
model H and later and MAGNA3-D. In all cases, mount the CIM
module in the master pump placed to the left.
For the purpose of redundancy, you can mount a second CIM
module in pump 2 for TPED and Multi-E (not MAGNA3-D). In that
case, all writings from the Modbus master must be sent to both
CIM modules.
