Instructions for the hand-held micro terminal of the fan
motor control system, TBLZ-1-75 SILVER C
1. General
The hand-held micro terminal is used for setting the motor
parameters of the SILVER C.
2. Installation
The hand-held micro terminal can be hung in the wall
mounting supplied, See illustration below. Mount the wall
mounting on a flat surface.
To lift the hand-held micro terminal out of the wall mount-
ing, slide it upward and then draw it out.

4. Function
The hand-held micro terminal communicates with the
motor control system via Modbus commands.
Factory and user settings are stored in the control system.
The settings are preserved in the memory even if the line
voltage is switched off or if the hand-held micro terminal
is removed.
If the hand-held micro terminal is not used for more than
10 minutes, the system automatically switches back to the
main menu. This reduces the risk of unintentional entry of
settings.
The possible settings and displays are shown in the table
on the next page. Scrolling up and down in the menu
is done by turning the adjusting knob on the hand-held
micro terminal, and selections are entered by pressing on
the adjusting knob. Modification of the selected values
is done by turning the adjustment knob. Select "Exit" to
leave the menu.
Standard Modbus address is Address = 54.
Standard baudrate is set to 38.4 Kbit/s.
The Modbus address and other motor parameters can be
changed in the hand-held micro terminal.
The standard Modbus address and baudrate can be
changed with the hand-held micro terminal in the follow-
ing way:
With the function selector switch (See illustration) set to
”0”, set the parameters to the required values with the
hand-held micro terminal. When the new values have
been set, set the function selector switch to position "1".
This activates the user-preset parameters.
The hand-held micro terminal will not work if the
baudrate is changed from the standard setting of 38.4
kBit/s and if the hand-held micro terminal is disconnected
from contact "C".
If the standard baudrate is changed from 38.4 Kbit/s and
the hand-held micro terminal is disconnected from its con-
nection, it will only be possible to restart communication
with the hand-held micro terminal if the function selector
switch is set to position "0". The baudrate will then be
set to 38.4 Kbit/s. If the function selector switch is subse-
quently set to position "1", the user-preset parameters
will be activated again.

Control
Selection of control signal
Control = HTERM
EC is controlled from the hand-held micro terminal.
External signals are ignored, including:
Start/Stop on Terminals 7 and 8 (ON/OFF).
The fire signal on Terminals 9 and 10 (Firemode) as well as the external control signal on Terminals 13 and 14 (0 – 10 V in).
Control = 0-10 V DC
EC is controlled from external control signals, including:
Start/Stop on Terminals 7 and 8 (ON/OFF).
The fire mode signal on Terminals 9 and 10 (Firemode) as well as the external control signal on Terminals 13 and 14 (0 –
10 V in).
External stop and stop from the hand-held micro terminal have higher priority than start from the hand-held micro
terminal.
HTERM / 0-10 V DC
FIRE Activate the Fire mode. "Fire" from the hand-held micro terminal or external input have higher priority than "Nor-
mal". Important! For high internal temperature inside the EC control system, the display window backlight is turned
off when "Fire" is active.
”1” = Fire /
”0” = Normal

Alarms Reset Alarm Is activated in order to reset alarms when the maximum number of restarts has been exceeded.
Alarm stop Shown when the motor has stopped due to an alarm.
Voltage low Shown when an alarm has been initiated due to excessively low line voltage.
Voltage high Shown when an alarm has been initiated due to excessively high line voltage.
Phase error Shown when an alarm has been initiated because one line voltage supply phase is missing.
Current high Shown when an alarm has been initiated due to excessively high output current.
Current limiting Shown when an alarm has been initiated because the current limiting function is active (e.g. if the ramp time is
excessively short or if the motor is overloaded).

5. Electrical connections
Connect the hand-held micro terminal to contact "C" in
the junction box (installed on the side of the fan mounting
frame) via a bus cable (cable type MPFK6S or the like) with
an RJ12/6-connector at both ends, see figures below.
Same order of colours

7. Alarm
For particulars of current alarms, see table in Section 4.
Alarms are reset automatically if the fault ceases to exist
and the EC control system starts up again.
If the maximum number of restarts has been exceeded the
resetting of alarms can take place by selecting "Reset
Alarm" in the alarm menu. As an alternative, the "Alarm
Reset" input can be short-circuited (Terminal 11 (Alarm
reset) and 12 ( ) in the junction box) or the line voltage
to the EC control system can be replaced.
8. Trouble shooting
Symptoms Cause Action
No values in the hand-held
micro terminal
– Display window off
The EC control system is switched off Start the EC control system
Modbus cable is defective Repair or replace the Modbus cable
Incorrectly set baudrate, communication speed Set the function selector switch in the junction box to posi-
tion ”0”
(See Section 4)
The RJ12 connector is not correctly connected Check the contact connections in both the hand-held micro
terminal and in the junction box.
In the junction box the contact ”C” should be used for con-
nection of the hand-held micro terminal.
Both the RJ12 connectors are active and can be used in the
hand-held micro terminal.
