When moving the gantry, observe the following:

► NEVER move the gantry by pushing with your hands against the placement head.

► NEVER push the gantry while the Z‑axis is lowered.

1.2 Preparatory work...

Purpose and scope

Before performing any preventive maintenance work, conversion work or service work, a procedure of

locking and tagging must be followed and warning signs must be attached if not stated otherwise. If

you do not need to switch off the machine, this will be clearly stated.

The procedure, when followed correctly, eliminates the possibility of an employee being injured.

NOTICE

Additional safety measures

This procedure represents the minimum lock out and tag out requirements for the machine during

preventive maintenance work and service work. Any additional safeguards needed to complete work

safely can be specified by facilities supervision, the safety officer, the safety committee and the health

department.

Description

Whenever it becomes necessary to isolate, control and release energy, the following procedure is to

be followed.

► Notify all affected employees.

► Switch off the machine and all additional devices. Carry out all normal stopping procedures:

ð Press the stop button.

ð Shut down the station computer.

ð Switch off the machine using the main switch.

► Isolate the machine from all its energy sources:

ð Shut off the compressed air supply.

ð Interrupt the voltage supply.

► Lock out the machine.

ð Attach a lock wherever possible.

Alternative: secure the circuit breaker

The lockout attachment can prevent the machine

from being switched on inadvertently.

► Switch off the machine.

► Set the circuit breaker to OFF.

 CAUTION!

The lockout attachment may only be

attached when the machine is switched

off!

► Attach the lockout attachment(1) to the cir-

cuit breaker.

► Secure the circuit breaker with a padlock.

NOTICE

Lockout attachment in the service box of your machine

On machines that are delivered from June 2016, the lockout attachment [03123101‑xx] is located in

the service box.

► Attaching warning signs:

If a machine can be locked, it must be.

However, there are situations where energy isolating devices cannot accommodate locks. In

these cases, the energy isolating devices must be tagged appropriately to warn employees that

the machine is currently de-energized for service purposes. The tag or label must be fastened

securely in a position visible from all sides and it may only be removed by the person who

attached it.

► Release of stored energy:

Energy stored as compressed air in the compressed air supply or electrical energy stored in elec-

trolytic capacitors must be released by appropriate means.

After switching off the machine, wait until the voltages have discharged and the compressed air

has released, so that work can be performed without any risk.

DANGER

Checking for absence of voltage!

► Before you start working, check the power supply for absence of voltage and observe the waiting

times!

► Testing the lock out:

The lock can be easily tested by pressing the Start button. The machine must not respond.

The following steps must be taken to restore the machine to operation.

► Check the workspace. Authorized employees should remove all of their tools and reinstall all

safety features.

► Notify all affected employees.

► Before removing even one lock or tag, inform all workers in the affected area that the machine is

going to be restarted.

► Remove all locks/tags.

Every authorized employee must remove his own lock and shut it away.

► Switch on the machine. Make sure that authorized staff check the equipment in operation to

ensure that all repairs were performed correctly.

Testing

Service personnel may test circuits by energizing them briefly without suspending the lock out / tag out

procedure. This may only be done when no other work is being performed by any other person on the

equipment being tested.

It is extremely important that all remote Start switches are tagged with the "Do Not Operate" tag to pre-

vent inadvertent operation of the equipment during these periods.

Responsibilities

●

It shall be the responsibility of the maintenance and service personnel to make sure this proced-

ure is adhered to.

●

It shall be the responsibility of the maintenance and service personnel's immediate supervisor to

instruct their personnel on this procedure.

●

It shall be the responsibility of the Safety Officer to administer the lock out / tag out procedure.

1.3 Notes on switching the machine back on

CAUTION

Residual voltages

► After switching off the machine, wait at least 10 seconds before you switch it back on again, so

that stored residual voltages can dissipate.

► Please note that longer waiting periods apply when working on the power supply.
