Description The XPSLCD1141 provides protection for machines with more than one opening to
guard. It produces a single pair of OSSD (OSSD A, OSSD B) safety outputs by
receiving safety and auxiliary outputs from up to four XUSLT/M/P/N family of light
curtains. The XPSLCD1141 is enclosed in a 75 mm W x 150 mm L x 110 mm H (3"W
X 5.8"L X 4.3"H) DIN box with two rows of removable terminal blocks. The mode and
configuration DIP switches are located inside the box. For DIP switch settings, see
Setting XPSLCD1141 configuration switches, p. 32.
The XPSLCD1141 module works with up to four independent safety sensing
devices identified as safety device 1, safety device 2, safety device 3, and safety
device 4. Each safety sensing device (light curtain) has two solid-state, current
sourcing type OSSD outputs identified as OSSD 1 and OSSD 2. The OSSD signals
conform to 24 V +/- 10 % indicating Machine Run and 0 V indicating Machine
Stop.
The XPSLCD1141 is primarily intended to work with the XUSLT family of light
curtains, but it can operate with other safety devices that test its OSSD output,
including the following other products: the XUSLM, XUSLP and XUSLN light curtain.
For the XPSLCD1141 to act as the primary safety device, the safety devices used
with the XPSLCD1141 module must be configured in the Automatic Start, interlock
mode and have their EDM/MPCE function disabled. The XPSLCD1141 also
provides connection for the safety device power, auxiliary, and start signals.
Response time The response time is < 1 ms. The response time is measured from the time when
any safety device transitions to the MACHINE STOP state to the time that the
XPSLCD1141 OSSDs are in the OFF state. The XPSLCD1141 controls it’s OSSDs
according to the state of the safety device OSSD inputs. The XPSLCD1141 outputs
are only active when all the selected safety device OSSD inputs are active.

Operating states
Principle The XPSLCD1141 module receives ouputs from up to four safety devices and
produces a single pair of OSSD outputs. The system consists of a DIN box with two
rows of removable terminal blocks, and is wired to up to four safety devices.
The Output Signal Switching Devices (OSSD A and OSSD B) are XPSLCD1141
components that connect to the machine control system. When a safety device
detection zone is interrupted, the XPSLCD1141 OSSD responds by going to the off
state.
The operating condition of an XPSLCD1141 safety device system is described in
terms of states. The following operating states exist for the XPSLCD1141.
Machine run The green MACHINE RUN indicator is lit, the OSSD outputs are on, and the
AUXILIARY output responds in a manner consistent with its set operating mode.The
protected machine is allowed to operate. Pressing and releasing the START button
has no effect.
Machine stop The red MACHINE STOP indicator is lit, the OSSD outputs are off, and the
AUXILIARY output is off. The protected machine is not allowed to operate.
Pressing and releasing the START button has no effect.
Interlock The yellow INTERLOCK indicator is lit, and the Start Required Lamp output is on.
The AUXILIARY output is off. The INTERLOCK state does not allow the protected
machine to operate until the START button is pressed and released.
Lockout (Fault) The yellow INTERLOCK indicator is blinking, and the Start Required lamp is
blinking. The AUXILIARY output responds in a manner consistent with its set
operating mode. This state does not allow the protected machine to operate until the
fault is removed and the START button is pressed and released or power is cycled.

Safety distance
WARNING
IMPROPER SET UP
Never install a XPSLCD1141 safety device system without regard to the safety
distance. If the safety devices connected to the XPSLCD1141 system are mounted
too close to the point of operation hazard, the machine may not stop in time to
prevent an operator injury.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
A safety device system must be mounted far enough from the machine danger zone
so the machine will stop before a hand or other body part reaches the hazardous
area. This distance is called the safety distance. It is a calculated number based on
a formula. See the user’s manual for the XUSLT, XUSLM, XUSLP or XUSLN safety
device for safe mounting distance formulas.

The XPSLCD1141 system operates directly from 24 V +/- 10%. Power to the
XPSLCD1141 must come from a dedicated power supply which must meet the
requirements of IEC 60204-1 and IEC 61496-1, Phaseo familly type
ABL8RPS24030/050/100.
When connected, the Start Required Lamp indicates when the XPSLCD1141 is
waiting for a signal from the start switch. The Start Required Lamp is an option and
is not required for operation of the XPSLCD1141.
The XPSLCD1141 power input return must be connected to the overall system
component returns. At the installation site, the power return of the XPSLCD1141
Start switch, EDM/MPCE monitor, Aux PNP, OSSD loads and Aux loads must all be
connected in common for proper system operation.
When EDM/MPCE monitoring is set to the inactive position, the EDM/MPCE In
terminal block, contact 4, must be connected to the system common return.
