3. Warning
JGGD001 can't be used with any machine that ejects materials
prevent the materials ejected leading to the injury.
Also can't provide the protection for below situation:
Failure to follow the instruction may result in a
serious injury or death
GB 28240-2012 Shears—Safety requirements
GB 28243-2012 Hydraulic press brakes—Safety requirements
GB 7247.1-2001 Safety of laser products--Part 1:Equipment
GB 4208-2008 Degrees of protection provided by enclosure(IP code)
Failure to follow the instruction may lead to minor or
moderate injury

1.6 Application Cautions
1. All the upper tools come with the same height and bending middle
center, the falling prevention equipment need to be mounted on the
worktable or upper tools
2. The JGGD001 is not used to monitor two bending machines placed in a
horizontal plane
3. If the workpiece block the light beams, JGGD001 stop immediately
the press closing, meanwhile any wavy material maybe cause the
unexpected lockout, so need mute the JGGD001 before materail interrupt
the beams. i.e. when the upper tool approaching the materail at 6-15mm
(as per bending machine overstroke) , control system should send
out the muting signal to JGGD001 receiver, and ensure the closing speed
<10mm/s according to the type 4 standards.
intervention shortly before the press closes completely, during the very
JGGD001 offers complete protection (finger and hands) from rapid
short time before complete closing with non protection, at the same time
JGGD001 function is muted(muting indicator ON)
●The switch keys should be kept by the designated person, and to
select the working modes according to the application requirements
●The protection function can't be performed to the bending machine
with press closing only at working speed, or too long overrun distance
● Prevent the JGGD001 device falling down
4
1. Must keep a certain distance between the JGGD001 beams and
upper tool, the distance referring to overrun distance measuring
value and distance of JGGD001 beam to upper tool
2. After installtion, only allowed to change the mould which has the
same overrun distance, otherwise need re-adjust JGGD001
installation position
3. JGGD001 used with PLC, PLC monitors related short circuited and
bypass state, provides closing signal and return signal, also process
the JGGD001 output OSSD1 and OSSD2
4. Installation and connection follow the instruction manual, complte
the safety regulations to ensure safety operation, not any change
allowed to circuit which will cause protection failure.
4. JGGD001 special mode enables the bending or wavy material or even
edge bending within a closed box. If the bending machine only closes at
work speed,or too big excess of stroke, JGGD001 won't provide protection,
i.e. won't prevent access to the hazardous area.
5. The bending machine control system must meet type 4 standards
requirements.
6. The protected machine must detect the danger status, and stop it

2.Basic Instruction
2.1 Terminology
Electro-sensitive protective equipment (ESPE)
Assembly of devices and components working together for protective
tripping or presence-sensing purposes and comprising as a minimum.
Detection Capability
actuation of the electro-sensitive protective equipment(ESPE).
EDM:
Means by which the electro-sensitive protective equipment(ESPE)
monitors the state of control devices which are external to the ESPE.
Lockout Condition:
Condition, initiated by a fault, preventing normal operation of the electro-
sensitive protective equipment(ESPE). All output signal switching
devices(OSSDs) and, where applicable, all secondary switching
devices(SSDs) are signalled to go to the OFF-state.
Muting:
Temporary automatic suspension of a safety function(s) by safety-
related parts of the control system.
On-state
current.
Response Time:
Maximum time between the occurrence of the event leading to the
actuation of the sensing device and the output signal switching
devices(OSSD) achieving the OFF-state.
Fault:
State of an item characterized by inability to perform a required function,
excluding the inability during preventive maintenance or other planned
actions, or due to lack of external resources.
Performance Level(PL e):
SLA-3 device comply with EN ISO 13849 PL e requirements,i.e. EN954
cat.4 requirements.
6
Failure:
Termination of the ability of an item to perform a required function
Note 1: After failure the item has a fault
Note 2: "Failure" is an event, as distinguished from"fault", which is a state.
Note 4: In practice,the term fault and failure are often used synonymously
Self-checking:
The device switches automatically into the "safe state" when it is faulty.
Standard Mounting Range:
Maximum distance between transmitter and receiver is 5 m, if exceed
the distance may lead to hazardous motion. For longer range please get
in contact with us.
Overrun Distance:
The distance covered during the overrun (e.g. by the ram of a press).
Start Interlock:
After initial operation or after a power supply interruption a renewed
"enabling" is blocked by the start interlock.The renewed release of the
switching unit is only possible by closing and opening of the start entry.
Box Bending Mode:
The E3 is muted during during bending process.
2.2 Usage
JGGD001 is the safety device specially applied to bending machine for
operator's protection which adpoted class 1 laser, A three-dimension
guarding area underneath the clamped upper tool, any intervention into
the area shuts down the closing movement of the press.
