1. InTRODUCTIOn
The following operating instructions merely serve as a supplement and
apply only in connection with the operating instructions of the Advanced
Energy power controllers Thyro-S and Thyro-A of types h1 and h RL1, as well
as Thyro-A h RLP1 as well as Thyro-AX of types h RL2 and h RLP2. Particular
attention must be paid to the safety instructions included in them.
1.1 GEnERAL
The bus module Modbus RTU can connect up to 8 power controllers of
type Thyro-A...1, Thyro-AX...2 or power switches of type Thyro-S...1 to a Mod-
bus master in any random order.
Several bus modules can be employed at one device. Each bus module
occupies one address on the Modbus.
The power supply of the bus module is provided by an external 24 V
d.c. power source (150 mA), which is fed into X11.1 (+) and X11.2 (ground)
(reverse battery protected). The 24 V d.c. supply must be ungrounded when
operating under SELV. Several modules can be operated at one power supply.
for EMC reasons, the earth connection to X11.3 must be as short as possible.
The Modbus connector with a 9-terminal standard allocation must be con-
nected to the socket X20.
1.2 SPECIfIC ChARACTERISTICS
• The bus module is a slave component
• Function control via LED
• 8 free digital outputs X1.5 to X8.5
• processing of actual values as float number in physical units
• C-rail assembly
• When the bus module is linked to Thyro-AX, please be aware that data trans-
fer is the same as for Thyro-A whereas special features or other additional
parameters are excluded from this.
