7000 SERIES
Safety Outputs OSSD1 and OSSD2 (F1) - Two independent electronic
switches provide the fail-safe outputs for connection to the machine
control system. Connections are at terminals J6/10 and J6/11 on the
control module. Outputs 'on' = 24V. Outputs 'off' = 0V maximum
switching current = 1A.
LED indicators mounted on the control module show the status of the
OSSD switches.
Safety Relay Outputs (F2) - a number of 7000 Series control module
types have on-board cross-monitored output switching relays. With
these models the electronic outputs are connected via links to the
inputs of the relay coils. Link electronic output switches to relay inputs
J6/10 to J6/6 and J6/11 to J6/7. The output relay switching contacts are
on terminals J6/4, J6/8 and J6/5, J6/9. Maximum switching power
110V, 2A.
Status Relay Outputs (F3/F4) - Relay switching contacts are provided
for guard status indication. The changeover output contacts from this
relay are non-safety. The status relay activates when the safety outputs
(F1) turn ON and de-activates when the safety outputs turn OFF.
Terminal connections are as follows: N/O contact J6/1, N/C contact
J6/3, Common 6J2. Maximum switching power 24V, 1A.
Mode (F5) - The mode setting switch is mounted on the control module.
The switch enables modes to be selected to suit the specific machine
applications. The dip switches can be set to provide the following
modes: 1) No interlock. 2) Start interlock. 3) Restart interlock. 4) Start
and Restart interlock. For settings refer to the table, Fig. O.

Green LED’s ON = OSSD1 and OSSD2 active ON
Red LED’s ON = OSSD1 and OSSD2 inactive OFF
Warning: When using the mute function select only mode 3
Restart interlock or, mode 4 Start/Restart interlock.
Warning: Mode switch changes have no effect until all electrical
power is removed from the control module and then re-
applied.
Warning: When setting up the light curtain, ensure that mode 1
No interlock is selected.

7000 SERIES
Range (F6) - The range setting switch is mounted in the control
module. The switch enables light curtain scanning ranges to be
selected to suit a specific application. The dip switches can be set to
provide the following ranges: 1) 0.5m to 1m 2) 1m to 4m 3) 4m to 15m.
For settings refer to Fig. N.
Mute indicator (F7) - A number of machine types require that a
monitored mute indicator be fitted when the light curtain is in a muted
condition, e.g. presses and press brakes. The 7000 system is fitted
with mute monitoring circuits and outputs for connection of a suitable
indicator. The indicator lamp must be 12V, 2.2 Watt to satisfy the
monitoring requirements. If no lamp or a lamp of incorrect power is
fitted at terminals J1/13 and J1/14 then the light curtain will not mute.
If light curtain muting is used but a mute indicator is not required for a
particular application connect a 78 Ohm 2.2 Watt resistor across
terminals J1/13 and J1/14.
Mute input (F8) - The complimentary input is provided at terminals
J1/11 and J1/12 for connection of suitable switching signals for muting
the light curtain. When both signals are active ON, and providing a
suitable mute lamp or ballast resistor has been fitted across terminals
J1/13 and J1/14 then the light curtain will mute, e.g. the guard output
switches will not respond to an interruption of the light curtain.
The mute switching signals must have the following polarity:
Mute signal A at terminal J1/11 = +24V DC
Mute signal B at terminal J1/12 = 0V DC

Warning: Range switch changes have no effect until all electrical
power is removed from the control module and then re-
applied.
Warning: When using the mute function select only mode 3
Restart interlock or, mode 4 Start/Restart interlock.
Note: Signals must be applied to both mute inputs at J1/11 and J1/12
within 200ms of each other. If this time is exceeded the system
will go to a lockout condition.

7000 SERIES
Start/restart (F9) - A suitable push button or key switch with a N/O
contact must be fitted across terminals J6/12 and J6/13 to reset the light
curtain when in the following modes; Start interlock, Restart interlock,
Start + Restart interlock.
Floating blanking (F10) - Floating blanking allows selected areas of
the detection zone to be disabled. The function is particularly useful for
those applications where, for example, a work piece is obstructing the
light curtain or possibly moving up and down within the curtain.
The 7000 Series has the capability of 1, 2 and 3 beam floating blanking,
offering much increased flexibility.
Floating blanking can be selected to allow one, two or three beam
obstructions within the light curtain to be ignored. The obstruction can
move or ‘float’ within the detection zone without initiating a stop signal
providing the obstruction does not interrupt more than the selected
number of ‘floating’ beams. If one beam blanking is selected, any
single beam in the light curtain can be blocked without the guard
outputs de-energising. If two beam floating blanking is selected any two
beam obstruction can be ignored. With three beam blanking any three
beams blocked will be ignored. The interrupted beams do not have to
be adjacent to each other.
Beam blanking is selected by connecting appropriate input signals to
the following terminals on the control module: +24V at J1/7, 0V at J1/8,
+24V at J1/9 and 0V at J1/10. For connection details refer to Fig. Q.

Note: The input signal must be applied within 200ms of each other. If
this time is exceeded the system will go to a lockout condition.
The signals may be applied during operation of the guard and
will take immediate effect. This feature can be used to increase
the integrity of a guarding application (partial muting).
Note: Beam blanking increases the size of object which is guaranteed
to be detected by the light curtain. (An increased ODC). When
selecting 1, 2 or 3 beam floating blanking the worst case ODC
should always be taken into account during the risk assessment
process. Check the position of the light curtain in relation to the
nearest danger point is in line with the requirements of
European Standard BS EN 999.

7000 SERIES
Monitoring (F11) - External Device Monitoring (EDM) inputs are
provided. If external relays are used it may be necessary to ensure the
relays respond each time the light curtain is interrupted.
If the monitoring function is not required for a particular application it is
necessary to link terminal J1/2 to J1/4 (0V) and J1/1 to J1/3 (+24V). If
the links are not fitted the light curtain control will go into a lockout
condition.
Power supply (F12) - Use a regulated supply +24V DC, 1.5A ±10%
Protect the +24V input with a 1.5A fuse (see note below). Terminal
connections: J6/16 = +24V, J6/15 = L- V and J6/14 = Ground.
Interlock indicators (F13/F16) - Yellow LED interlock indicators are
provided on both the transmitter unit and in the control module. When
the LED’s are illuminated the 7000 system is in a lockout condition e.g.
latched in the 'off' state by interlock function F5.
Guard ‘clear’ indicator (F14) - A green LED indicator mounted on the
transmitter unit illuminates when the light curtain is clear and
operational ON.
Guard ‘block’ indicator (F15) - A red LED indicator mounted on the
transmitter unit illuminates when the light curtain is blocked and non-
operational OFF.
Safety relay input (F17) - Some 7000 Series control module types
have on-board cross monitored output switching relays. With these
models the electronic outputs are connected via links to the inputs of
the relays. Link output switches to relay inputs J6/10 to J6/6 and J6/11
to J6/7. The two output relay switching contacts are on terminals J6/4,
J6/8 and J6/5, J6/9. Maximum switching power 110V, 2A.

Note: Both monitoring signals must be applied within 200ms of each
other. If the time is exceeded the system will go to a lockout
condition.
Note: OSSD current is an addition to the control units quiescent
current (no load) For example if the electronic OSSD’s are
consuming the maximum rated current OSSD1 = 1A & OSSD2
= 1A then the input fuse must be increased as follows 1A + 1A
+ 1.5A (quiescent current). Therefore fuse rating = 3.5A

Mirror Units
Two or three sides of a machine can be safeguarded with a single light
curtain by using mirrors to deflect the light curtain’s infra-red beams.
(See appendix 2 for installation guidance).
The Smartscan mirror system provides a sturdy floor mounting kit
together with an aluminium column for mounting the mirror. The mirror
assembly simply slots onto the column and can be adjusted to the
height required for the application.
The special mounting stand enables the mirror unit to be rotated
through 360 degrees while also allowing full adjustment in all axes.
