Shielding
The use of shielded cables is normally not needed but offers high protection against electromagnetic
interferences, especially high frequencies. However, the effectiveness of the shield depends on care-
ful installation of the line.
If shielded cables are used, the shield should be placed at “PE” on at least one side (preferably on the
master connection). The occurrence of compensating currents may have to be considered if the shield
is contacted on both sides.
Shield connection correct Shield connection incorrect
Information
If any matters are unclear, please contact our V-STE support department for control systems -
ventilation technology. The information sheet "Network structure of MODBUS" R-TIL08_01 contains
detailed information about "MODBUS".
5.10 Addressing member MODBUS Master Interface
Up to 32 members can be connected at the MODBUS Master interface.
No other components are required for the patented automatic addressing (activation see menu group
MODBUS Master: Auto Addressing). Only the connections “ID1” and “ID2” of the Slave members are
connected additionally next to the bus connection and at the “ID” connection of the MODBUS Master
for this.
The “ID” connection of the MODBUS Master must be connected to the “ID1” or “ID2” connection of the
first Slave member. This is recognised as a result and occupied by address 1.
For the following users the connection “ID1” or “ID2” of a Slave user respectively is connected with
connection “ID1” or “ID2” of the next Slave user.
The automatic addressing of other users is initiated by the previous user via this connection.
The individual members can be addressed in advance without this device by an external terminal or a
PC.
Alternatively, manual addressing with free assignment of the address is possible (see Manual
addressing).
Information
•If a repeater is necessary and automatic addressing should be carried out, only the repeater of the
Z-G-1NE type can be used, only it can relay the addressing signal.
•Depending on the version, the connections for MODBUS “A (D+)”, “B (D-)” are available single or
double at the Slave members. These are connected with each other internally electrically.
•The connections for the automatic addressing “ID1” and “ID2” are not directly connected with each
other internally. These may not be bridged; any order of connection is possible.
•When using the connection box the cable shield of the CAT5 cable is internally connected to “PE” by
an RC element.
•The communication parameters are fixed preset, see programming menu group MODBUS Master.

0 - 10 V signal). The controller configuration is automatically carried out during selection of the
application related mode of operation. The factory presets in accordance with the mode of operation
are based on many years of experience, which is suitable for many applications. Under special
circumstances, these can be individually adapted (see Operating Instructions / Controller Setup:
“Controller Configuration”).
The purpose of the device is to reach and maintain the target values set. To accomplish this, the
measured actual value (sensor value) is compared with the adjusted target value, and the controlled
value (modulation) is deduced from this.
By selection of the mode the function for control circuit 1 is determined, this influences the following
outputs (factory setting):
1. Analog output “A1” 0 - 10 V with function
| 2A | (see Electrical installation).
2. MODBUS Master interface “1A” + “1B” with function
| 2A | (see Electrical installation).

6.2 Operation with a second control circuit
The function for control circuit 1 is determined by selection of the mode. This influences the output
with function
| 2A | .
A second control circuit with separate actual value measuring and separate output can be activated
additionally if required.
Control circuit 2 influences the output with function
| 8A | .
•Analog output “A2” (factory setting) see IO Setup
•MODBUS Master interface see member menu
Operation with a second control circuit is not possible in the following modes:
1.01 , 1.02 , 2.03 , 4.02 , 4.03 , 5.02
The following modes which are pre-programmed to operation with a second sensor can be reprog-
rammed to operation with a second control circuit:
2.04 , 2.05 , 3.03 , 3.04
The second control circuit is activated by the “E2 function” for the second analogue input “E2” (see
menu group “Base Setup”).

Following restrictions apply for the control circuit 2:
•The “Manual Mode” function in the “Setting” menu group only influences control circuit 1!
•The fuction Limit (see IO Setup
| 3D | and Controller Setup) influences both control circuits simulta-
neously.
•The “Max. Speed” setting by a digital input (see IO Setup
| 11D | ) simultaneously influences both
control circuits. I.e. at “1.Max. Speed” and at “2.Max. Speed”.
•The controller configurations (KP, KI, KD, TI see Controller Setup) are identical for both control
circuits. Fine adjustment is possible for each control circuit by the separate “Pband” setting.
