Installations
Amplifier unit mounting
● Installation: Hang up the backside holder on the DIN rail
and press the unit toward the DIN rail.
● Removal: Slide the back part of the unit as the ① figure
and lift up the unit as the ② figure.
Amplifier unit connection
● Remove the side cover at the connecting side as the
figure ① and connect the side connector as the figure ②.
● After mounting the unit on the DIN rail, push gently
both units to fasten each other.
※Make sure that connections between the unit case
and connectors correctly. Improper connection may
cause malfunction of channel setting and mutual

Teaching sensitivity setting (Auto-tuning, One-point, Two-point, Positioning)
● How to enter into sensitivity setting mode in RUN mode
Press the key once and the selected teaching mode parameter flashes twice on the SV display part.
※ Refer to [B-12 to 14] pages for each teaching sensitivity setting.
● Teaching should be executed for over 3 sec.
※ If teach mode is executed for less than 3 sec., teach mode parameter flashes twice and be on standby to execute
completion of teach mode.
● Current incident light level is indicated on PV display part while teaching is in the process.
● If incident light level is received under 10 digit while teaching is in the process, it is automatically returned to RUN
mode and previous setting value is retained after [ ERRL] flashes twice.
※If there is no key operation for 60 sec after entering into teaching mode, it is automatically return to RUN mode.
1) Auto-tune teach mode
※ Suitable when incident level of sensing object is not stable or when sensing fast moving objects.
※ Auto-tune automatically sets the sensitivity using the average value of the incident light level within a certain time period.

Energy saving function [ ESAV]
A function to save unit's power consumption by reducing power supply to display parts in case of no setting input
within 60 sec.
● Selectable from 2 power saving modes
- Normal mode [ NOR] : Main output indicator(OUT), PV/SV display part ON
- Energy saving mode 1 [ 1SAV ] : Main output indicator(OUT) and PV display part ON
- Energy saving mode 2 [ 2SAV ] : Main output indicator(OUT) ON
Light ON / Dark ON switching function [ LDON]
A function to set Light ON - control output is ON when incident light level is higher than setting value Dark ON -
control output is ON when incident light level is lower than setting value.
Communication enable / disable setting function [ COMM ]
A function to set communication write [enable( ENA) / disable(DISA)] for Slave amplifier units while certain instructions
(Load/Save/Copy) or Group teaching is in progress by the Master amplifier unit.
Lock function [ LOCK ]
Two types of key lock setting are available in order to prevent SV changes due to careless.
● In case of [ LOC2 ]mode, it is required to disable the lock function first to enter into parameter mode.
Data Bank setting
A function to save settings for group amplifier units in each data Bank by using Master unit's command or by adjusting one
amplifier unit's setting and to load required data Bank when it is necessary without resetting for each unit's parameters and
setting values.
● LOAD [ LOAD ] : Loads preset dataBank( BAK0, 1, 2) and applies it to the amplifier unit.
Detailed Bank parameters can be read and changed.
● SAVE [ SAVE ] : Saves one amplifier unit settings in one of dataBank( BAK0, 1, 2).
● COPY [ COPY ] : Copies the currently loaded Bank by Master’s instructions to the other amplifier unit (1:1) or the whole
amplifier units (1: M).
● LOAD ALL [ LDAL] : Selects one dataBank by Master’s instructions loads it to entire group units.
● SAVE ALL [ SVAL] : Selects one dataBank by Master's instructions and saves it in entire group units.
※
Up to 3 dataBanks are available [ BAK0, 1, 2] and each Bank can be read and changed.
It allows users to detect three different sensing objects using one amplifier unit without resetting each parameter.
※
For BF5-D1- , three dataBanks are available ([ BAK0 ], [ BAK1] and [ BAK2]) so that three different sensing

Group teaching
A function to set the sensitivity of Slave amplifier units according to the command of Master amplifier unit(a certain
amplifier unit) in a successive and collective way.
When group teaching is executed,
the Master unit transmits teaching
command to each Slave unit and
channel No. and " OK " is displayed.
Ex) In case of 8 channels
Select " NO " and press key
to return to RUN mode.
The Master unit starts teaching after
teaching command transmission to
Slave unit is completed.

Dual display / Single display common features
Program mode function
Amplifier units connection using side connector
In case multiple amplifier units are connected, the power supply for one unit will feed all connected units.
Auto channel setting function
● The channel for each amplifier unit - connected by side connector - is automatically set in a certain direction ( →) as soon
as power is supplied. Channel number is increasing one by one.
● Auto set channel can be checked in channel parameter in program mode.
● In case of BF5R-S1- , auto set channel can be checked only when initial power is supplied. (Not available afterwards).
● Channel range : 1 to 32(applied the same to all models)
※ Note that auto set channel cannot be changed and the channel No. of each amplifier unit is not saved in case of
power OFF.
Mutual interference prevention function
A function to set different light receiving time for each amplifier unit in case of adjacent fiber cable installations in order to
prevent mutual interference occurring. (Set automatically when power is turned ON.)
※ Mutual interference function is allowed up to maximum 8 amplifier units regardless of the unit model and response time.
High peak, low peak function
A function to monitor the high/low peak value of incident light level. The monitored high/low peak value can be initialized.
Error code Cause Troubleshooting
ERRL In case incident light level is below the min. range when
teaching. Increase the incident light level above min. range.
ERR In case overcurrent inflow occurs into output circuit. Remove overcurrent due to overload.
ERB
● In case Slave is failed to execute Master's instructions
due to unstable communication line connection during
Group Copy / Load / Save / Teaching.
● In case other communication errors occur
● Check amplifier unit's connection again.
● Check circuit and hardware around side connector.
