Supply groups

A supply line represents a supply unit. For heating power monitoring and for distributed switch-on (zoning), it must be known which zone is connected to which supply line.

As a rule, the supply consists of one, two or more phases of a three-phase network. Heating tapes connected between phase1 and neutral conductor must get a 1 in the MParam.SupplyLine. Heating tapes connected between phase 2 and neutral conductor are assigned a 2 in the Mparam.SupplyLine. Heating tapes connected between phase 3 and neutral conductor are assigned a 3 in the Mparam.SupplyLine. Multiphase heating tapes (two-phase or three-phase) are assigned a 4.

Supply groups 1:

L2-N

2

L3-N

3

Multiphase (L1 - L2; L2-L3; L1-L2-L3; etc)

4

If there is more than one supply for the heaters, there must be at least one power measurement terminal for each supply. This can be the case, for example, with several extruders that are operated on one control system.

Supply groups 2:

The numbering of the subsequent supply groups (supplygroups) is consecutive. I.e. Supplygroup 2 has assigned SupplyLine 5,6,7,8.

Supply groups 3:

The constant cnPfwAppSupplyLast must be at least equal to the largest value of the Mparam.SupplyLine. This constant defines the size of the TempCtrl_ST_TcPfw_SupplyParam array. The SupplyParams represent essential properties of the output generation, like the PWM cycle time, minimum and maximum switch-on time.
