Power Supply
T05 is supplied with 18 V - 35 V DC via the two terminals marked “-/+
on the PC board corresponding to terminals 11/12 in the Block
above. The supply GND terminal is connected directly to the I/O GN D
and the Functional Earthing terminals. Alternatively, a 48 V supply
be connected between terminals 28 (+) and 27 (-), which renders DI6 un-
fuse must be provided on the positive supply with a rating of max
A, Quick Blow. The contacts of the two power relays can carry max 10 A at

can alternatively be powered from 230 V mains v ia a built-in transformer.
This
connection is shown on next page and must use a separate Pg16 cable
gla
nd and include an external power switch and a fuse of max 10 A. The
current
of the two digital outputs are, howev er, limited to some 10 mA each by
the transformer capacity.
Installation and Start-Up
The
T05 is typically wall mounted using the four corner holes. This mounting
does not affect the IP 65 case sealing. Cables must be entered via cable
glands
that are adequately tightened to prohibit the cords from being pushed
into/pulled
out of the unit. The unit is a Class II equipment intended for
Installation
Category II. Please follow the instructions described under “Safety
Precautions” on page 18.

Address Setup
are two ways of defining each of the 63 addresses for a T05 module,
through jumpers or by the internal EEPROM in the module. If any combi-
of jumpers except all six installed or all six removed is used at power-up,

0/ - A5 contribute their values 1, 2, 4, 8, 16 and 32 when

jumpers installed would generate the invalid address 00, and all jumpers
would be equal to the "reserve" address 63. In this case, the module

address number. Should none be

and used for all subsequent communications until this
is changed or a new power-up is performed. Changing the RAM
can be done from the master or from the local PLC program in the
but make absolutely certai n to avoid collision with other modules on
T05 CLIMATE CONTROLLER MODULE p 6
A
special feature is added to help recover "lost" modules, i.e. when an unknown
bit
rate and/or address is selected or the PLC runs a program that erroneously
alters
parameters affecting the communication. To recover such a module,
carry out the following steps:
1.
Disconnect power.
2.
Remove
all address jumpers except for A0 and A1 but
rotate
these two
jumpers 90
from their normal position. Please refer to the figure below.
3.
Apply
power. The module will now communicate at 4800 bits/s using
address 63 with the PLC and any options disabled.
4.
Check and reconfigure the module for proper operation.
5.
Restore correct jumper address.
Analog Outputs
The
analog outputs are controlled by values entered in two parameters hex
0/C
and 0/D
and provide pos it i ve voltages between 0 V and 10 V at loads up to 5
mA.
An individual control flag in parameter
0/4/0/
5 changes the range
to 2 - 10
V for either output to suit some types of valves etc.
Analog Output Overrange / Underrange
Normal
12-bit AO control range is hex
0/0/0/0/ - 10/0/0/
= 4097 values within 0 - 10
V
for both AO. AO2, however, being a 10-bit converter will set an output to one
of
1025 values within 0 to 10 V. This means that typically 4 consecutive 12-bit
values,
e.g.
0/0/0/4
- 0/0/0/7, in String Mode or double-byte Data Mode will
generate the same output. (Single-byte Data
Mode permits only 128 different
levels).
Negative
control values, hex 8
0/0/0/ - FFFF (or in Double Data Mode hex 2
/0/0/0 -
3FFF) will set the output to zero (or 2 V if this offset is active).
Positive values hex 1
0/0/0/ - 7FFF will set the output to 10 V.
Analog Inputs
two inputs are single-ended, meaning that a signal source or transducer
can measure a full-scale positive voltage of 0 - 10 V or 0 - 2 V with
to ground with an input impedance of 1 M
and a resolution of 12
In order to directly measure 0 - 20 mA or 4 -20 mA, an internal 100
load
is provided. A three-pin jumper area is found close to the AI1 terminals.
jumpering the position shown on page 4 as 20mA, the resistor is connected,

to the pot for special control, readable as DI7 in parameter

While
button is pressed, the pot cannot be read, and parameter 3B retains the last
T05 CLIMATE CONTROLLER MODULE p 8
Digital Inputs
Four
digital inputs sensing contact closures are available, marked DI1 - DI3 and
DI6.
They can be manipulated in software to provide a 0-to-1 or 1-to-0 change
only
when their level has been stable for more than a preset time from 1 ms to
1
s. This "debounce" time is preset in EEPROM parameter nr 3, refer to page
17.
Digital input status is available by reading paramet er
0/9.
Two additional
inputs, DI4-5 double as outputs, see below.
The
signals may also be inverted or held in an "edge-trig" register until read by
a
communication. These functions are enabled for individual inputs in par-
ameters
/0A and /0B. Note that repeated communications with the DI parameter
will
not clear such an edge flag until you undertake an access to another
address or parameter.
DI1 also includes a pulse
counter, incrementing on each positive edge of the
input
at 500 Hz max rate. The counter parameter 1
0/ may be read, preset or
cleared at any time. It folds over to 0 after 65536 pulses.
Digital Outputs / Relays
Two
digital outputs, DO1 and DO2 are available, each with 300 mA output
transistors. These outputs are connected to digital inputs DI5 and DI4,
respectively.
Thus, if the outputs are inactive then DI4 and DI5 may be used as
inputs. All outputs are controlled by
bits in parameter
0/8, accessible from the
central, or as DO bits from the PLC in the T05.
DO1
and DO2 are short-circuit protected, automatically switching on and off
until the short is removed. The shorted status is reported in parameter
0/8.In addition, two more digital outputs, DO3 and D O 4, control two power relays,
RL1 and RL2, with 10 A / 230 V AC contacts.
An
extra miniature relay is included in some versions, e.g. as an alarm output.
Both
the normally closed and the normally open contacts are available on the
separate,
3-pole terminal. These contacts can carry max 1 A and are not
intended
for switching mains voltages. The relay is operated as DO6 by setting
bit 5 in parameter
0/8.
In some versions of T05, a
fourth
relay is installed replacing the mains
transformer.
The relay is normally closed and will open w hen the digital output
DO7
is activated. The relay contact, 10 A at 230 V AC, is connected to
terminals 30 and 31, which are used for 230 V mains in other versions.
It
may be necessary to switch off outputs if communication from the central
should fail. A timer in parameter
0/3
will turn off outputs after preset, non-zero
time of max 65 s. PLC masked outputs are not affected.
Indicator LEDs
extra Digital Output, DO5, controls a red indicator LED. It can be set or
in parameter
0/8
just as the other outputs from the central or as bit
LEDs show operation of the SIOX bus as described in the “SIOX System

Parameter Setup
The
T05 contains two types of memory: RAM for temporary storage for as long
as
the module is connected to a po wer supply, and EEPROM for long-term
storage
of working modes, parameters and initialization values after a power
disconnect. At power-up, the EEPROM variables are automatically copied to
the
RAM, and the information is used to control the module. All EEPROM setup
values may be copied again if data = FFFF is written to the
first
paramet er
(number
0/0/). This initiates a full soft reset, using previous EEPROM value for
this parameter.
By
using String Mode commands, any variable may be read or modified at any
time,
either temporarily in RAM or permanently in EEPROM. In the latter case,
the
corresponding RAM cell is modified as well. Information in controlling
parameters immediately affect the function of the module.

Parameters 16-17, Real Time Clock
The
software controlled RTC depends on the internal CPU clock for accuracy.
To
optimise its speed, the first half of parameter 16 can be increased or
decreased
a few steps (in EEPROM for permanency). Alternatively the RTC
parameter
17 may be rewritten (in RAM) at any time, which also restarts the
10ms counter (second half of parameter 16).
Any
of the PLC instructions DATE (DATM...DATS) changes, when first run,
parameter
16 from a 65536 seconds counter to a minutes + seconds register
with a maximum value of hex 3B3B (59 minutes, 59 seconds).
Parameters 7
0/-7F, AI/AO Trim Values
These
parameters are preset from factory. To avoid inadvertent changes they
can
only be mo difi ed if 8xxx is set in param eter
0/0/.
Trimming can be done in
RAM
first and transferred to EEPROM only w hen improvements are achieved.
Safety Precautions
