zThis is a Class A instrument. In a domestic environment this instrument may cause radio
interference, in which case the user is required to take adequate measures.
zThis instrument is protected from electric shock by reinforced insulation.
So please arrange reinforced insulation to the wire for input signal against the wires for
instrument power supply, source of power and loads as far as possible.
zThis instrument is manufactured on the assumption that it is used in the condition of being
mounted on the instrumentation panel. Therefore, take the necessary measures on the

etc.
zAlways observe precautions described in this manual. Otherwise serious injury or
accident may result.
zConduct all of the wiring in accordance with the local codes and regulations.
zInstall a protection device such as a fuse, etc. in the power supply, input or output line, if
necessary.
zDo not allow metal fragments or lead wire scraps to fall inside this instrument. This may
cause electric shock, fire or malfunction.
zFirmly tighten each terminal screw at the specified torque. Otherwise electric shock or fire
may result.
zDo not place any obstacle around this instrument in order not to impede radiation of heat.
And do not close ventilation holes.
zDo not connect wires to unused terminals.
zBefore cleaning the instrument, always turn off the power supply.

1. TRANSFER TO MODE
Initialization is to set parameters relating to instrument specifications (input type, input range, alarm
type, etc.) and those relating to instrument characteristics (setting limiter, alarm differential gap, etc.).
1.1 Transfer to Initialization Mode
The section in each picture is dimly lit.
1. Turn on the power to this instrument. Thus, the input type, input range and PV/SV display
mode change in this order.
2. Press the SET key for two seconds with the instrument set to PV/SV display mode to change the
instrument to parameter setting mode.
For details on parameter setting mode, see the instruction manual for CB103/CB403/
CB903 (IMCB11-E

The section in each picture is dimly lit.
1. Transfer to Initialize code selection after each parameter is set.
2. Press the <R/S key while pressing the SET key for two seconds in the Initialize code selection
state to transfer to PV/SV display mode.
3. Press the SET key for two seconds in the PV/SV display mode state to transfer to parameter
setting mode.
4. Press the SET key to transfer to the set data lock function display (LCK).
5. Press the <R/S key to brightly light the thousands digit on the set value (SV) display unit.
See 4. on P. 1.
6. Press the DOWN key to set the numeric value corresponding to the thousands digit to 0 from 1.
7. Press the SET key to transfer to the next parameter. As a result, the Initialization mode lock
state setting becomes effective.

2.2 Procedure for Setting Each Parameter
[Example of changing the setting]
When the display unit shows SL1 (Input type selection) in initialize code 0, the following procedure is
for changing the input type from K to J.
The section in each picture is dimly lit.
1. Change the instrument to the initialize code selection display.
See 1.1 Transfer to Initialization Mode on page 1.
2. As SL1 belongs to the group of initialize code 0, do not change the initialize code (the units
digit) but press the SET key to change to SL1.
