Instructions for the hand-held terminal
of the fan motor control system, TBLZ-4-75
SILVER C
1. General
The hand-held terminal TBLZ-4-75 is a control panel with
touch screen that is used to set motor parameters on
SILVER C. The hand-held terminal communicates with the
motor control system via a Modbus interface.
2. Installation
The hand-held terminal can be mounted on a flat surface
using screws or magnets.
There is a keyhole slot at the rear of the hand-held termi-
nal for mounting with a screw, which is inserted on a flat
surface, see the diagram to the right. Use a screw with
a maximum diameter of 3.5 mm and a max. length of 9
mm.
The black shock-absorbing casing comes with two mag-
nets that make it possible to hang the hand-hand terminal
on a vertical, flat and metallic surface.

4. Function
4.1 Start screen
The motor control system’s function selector switch should
normally be set to position 1 for control 0-10 V, but if the
fan is to be controlled or settings are to be made via the
hand-held terminal, the function selector switch should be
set to position 0.
If the screen lock is enabled, press on the screen once to
open the start screen.
The start screen provides access to basic functions, for
example, fan speed, type of drive, supplied power and
type of control. Enabled alarms and warnings are shown
at the top of the screen. An alarm clock shows that an
alarm is enabled. A warning sign shows if there is an
active warning. Press the alarm clock or warning sign to
navigate to the list of alarms/warnings.
To change set point values, press “Set point” on the start
screen.
The fan icon shows if the fan is running or stopped. Press
the fan icon to start or stop the fan.
4.2 Menus

4.3 Set point
The set point screen can be used to change set point
values. Use the numerical keypad displayed to select set
points and press OK to confirm the new set point.
Factory and user settings are stored in the motor control
system. The settings are preserved in the memory even
if the mains voltage is switched off or if the hand-held
terminal is removed.
4.4 Modbus communication
The hand-held terminal communicates with the motor
control system via Modbus RTU, with the following
Modbus settings:
• Autodetect = Autoscanning to find the address, must
be set to On.
• Address = Modbus address.
• Baud rate = 38.4
• Parity = None.
• Stop bits = 1/2.
The motor control system has two Modbus settings, one
preset and one alternative.
Preset Modbus setting:
• Address = 54.
• Baud rate = 38.4
• Parity = Even.
• Stop bits = 2.
Alternative Modbus setting. Set at the from the factory:
• Address = 0.
• Baud rate = 115.2 kbps.
• Parity = Even.
• Stop bits = 2.
It is possible to change the alternative Modbus setting
with the help of a Modbus register.
The motor control system automatically detects whether
communications occur via the preset or alternative
Modbus setting. If no communications occur via the
preset Modbus setting after 10 seconds the motor control
system searches for the alternative Modbus setting and
vice versa.
4.5 Change Modbus address
Wait 10 seconds so that settings can be saved before the
hand-held terminal is switched off.
The motor control system will search for the preset
Modbus setting for 10 seconds before searching for the
alternative Modbus setting.
4.6 Shock-absorbing casing
The hand-held terminal is equipped with a silicone casing
that protects against shocks, oils and dirt.
