1 Introduction
This instructions handbook addresses every user of the chamber (also referred to as
the product). To use the chamber safely, first read and understand this entire hand-
book. If you are unsure about a topic, ask your supervisor or contact Rohde & Schwarz
customer support.
The instructions handbook helps you to use the chamber safely and efficiently during
its entire lifecycle; installation, operation, maintenance and disabling. If you are only
involved in one part of the lifecycle, focus on the chapter about that topic. But always
get a deep understanding of the safety aspects described in Chapter 2, "Safety",
on page 10 before starting.
The chapter titles give a clear idea of the lifecycle stage and the tasks described. For
example, if you are an operator, most activities intended for you are described in Chap-
ter 7, "Operation", on page 42. If tasks are restricted to certain roles, these roles are
mentioned at the beginning of the chapter that describes the tasks. The roles are
explained in the glossary.
Abbreviations and frequently used terms are explained in the Glossary at the end of
this handbook.

2.1 Intended Use
The chamber is intended for radiation testing of electronic components and devices in
industrial, administrative, and laboratory environments, see Chapter 6.1, "Choosing the
Operating Site", on page 24. Use the chamber only for its designated purpose, as
described in this handbook. Observe the operating conditions and performance limits
stated in the data sheet. If you are unsure about the appropriate use, contact
Rohde & Schwarz customer support.
2.2 Residual Risks
Despite the inherent safe design measures, safeguarding and complementary protec-
tive measures adopted, residual risks remain because of the following facts.
Chamber is heavy
The weight of the chamber without accessories and antenna cage is approximately
34 kg. In total, the chamber can weigh up to roughly 45 kg. If the chamber drops on a
person, it can cause severe injuries, even death.
If the chamber is mounted in a rack on rails, the center of gravity moves with the cham-
ber when you slide it out of the rack. If the rack topples, it can cause severe injuries,
even death.
Residual Risks

Safety
R&S®TS7124AS
11Instructions Handbook 1179.2948.02 ─ 01
Door of the chamber is heavy
The center of gravity moves with the door when you open it. If the chamber topples, it
can cause severe injuries, even death.
If the chamber sits on rails in a rack, the shift of the center of gravity is enhanced when
you slide the chamber out of the rack and open the door at the same time.
Moving door
When you trigger the closing of the door, the door starts closing with reduced force. A
built-in soft-close mechanism prevents the door from closing with full force as long as
the gap is large enough to put a finger in it, maximum 8 mm. But if this safety mecha-
nism fails, and the door closes with full force with a finger between the door and door
frame, the finger is crushed. Even the loss of the limb is possible.
The safety mechanism is described in detail in Chapter 3.2, "Automatic Emergency
Deactivation", on page 15.
Accidentally disabled soft-close mechanism
A safety cap (Figure 6-10) on the [X21] connector protects the pins of this connector.
The connector is at the rear in the supply and control panel, labeled 3 in Figure 4-3. If
the safety cap is missing, an accidental short-circuit of these pins can disable the soft-
close mechanism. Without safety mechanism, the door closes completely with full
force. A finger between the door and door frame is crushed. Even the loss of the limb
is possible.
Therefore, always keep the connector [X21] covered; either by the safety cap, or by the
connector of the push-button switch unit (Figure 4-4).
Electrically powered
The risks, requirements for installation and safety measures are described in "Connect-
ing to power" on page 12.
Pneumatically operated door
Supply the compressed air for the pneumatic system at a pressure of 6 bar. If the pres-
sure exceeds the limit of 7 bar, the chamber operates under unspecified conditions.
When operating the door at > 7 bar, uncontrolled situations can occur, causing injuries
like crushed fingers. See Chapter 6.4, "Connecting Compressed Air", on page 31.
2.3 Potentially Dangerous Situations
Potentially dangerous situations can occur during the following activities.
Transport
Wear appropriate protective clothing that complies with your local rules and regula-
tions. If you are unsure of which equipment to use, ask your safety inspector. For
example, gloves help to keep a tight grip on the handles when carrying the chamber.
Potentially Dangerous Situations

Safety
R&S®TS7124AS
12Instructions Handbook 1179.2948.02 ─ 01
Without gloves, you have less friction and your grip can slip if your hand is oily or wet.
As a result, the chamber can drop and crush your foot or someone else's. Therefore,
always wear safety shoes with toe cap when moving the chamber.
Always secure the door when moving the chamber, even if it is only for a short dis-
tance. See Chapter 5.3, "Securing", on page 22 for details on how to do it properly. If
the door is not secured and opens while you are carrying the chamber, the center of
gravity shifts. As a result, one of the carrying persons suddenly has to bear a much
larger portion of the weight. When the sliding door hits its end position, the sudden stop
results in a powerful thrust. If the person cannot manage the extra weight or loses grip
of the handle, the chamber can drop and cause severe injuries, even death.
The chamber is heavy. Do not move, lift or carry the chamber by yourself. A single per-
son can only carry a maximum of 18 kg safely depending on age, gender and physical
condition. So at least 2 people are required. With fewer people, you risk injuries, rang-
ing from back injuries from too heavy lifting to severe injuries like contusions or limb
loss if the chamber is dropped.
If you suffer from medical problems such as spinal and back disorder, or if your physi-
cal state is not compatible with lifting a heavy chamber, do not participate in carrying it.
Use the handles to move or carry the chamber. See Chapter 4, "Machine Overview",
on page 17 to see where the handles are located.
To move the chamber safely, you can use lifting or transporting equipment such as lift
trucks and forklifts. Follow the instructions provided by the equipment manufacturer.
For detailed instructions, see Chapter 5.1, "Lifting and Carrying", on page 21.
Setting up
Place the chamber on a sufficiently sturdy support that can bear the weight of the
chamber. Secure the support against toppling over, for example by fixing it to the floor.
Observe the specifications of the manufacturer. Always place the chamber on a flat
and level surface with the bottom of the chamber facing down. If the support is not
sturdy enough, it can collapse. If the support is not level, the chamber can slide and
drop from the support. In both cases, severe injuries are possible, even death.
When the chamber is positioned, secure the chamber as shown in Figure 6-2. If you do
not secure the chamber, the chamber can topple when opening the door, as described
in "Door of the chamber is heavy" on page 11.
Set up a restricted area that only trained personnel are allowed to enter. In the restric-
ted area, mark the space on the floor that is required for fully opening the door.
Route cables carefully and ensure that nobody can trip over loose cables.
For detailed instructions, see Chapter 6.3, "Mounting the Chamber", on page 26 and
Chapter 6.7, "Defining Zones of Restricted Access", on page 38.
Connecting to power
The chamber runs on 24 V DC supplied by an external power supply unit that is inclu-
ded in the delivery. The power supply unit has overvoltage category II. Connect it to a
fixed installation used to supply energy-consuming equipment such as household
Potentially Dangerous Situations

Safety
R&S®TS7124AS
13Instructions Handbook 1179.2948.02 ─ 01
appliances and similar loads. Be aware of electrical risks, such as electric shock, fire,
personal injury or even death.
Take the following measures for your safety:
●Before connecting the power supply unit to a power source (your mains grid),
ensure that this source matches the voltage and frequency [INPUT] range indica-
ted on the power supply unit.
●Only use the external power supply unit that is delivered with the chamber. It com-
plies with country-specific safety requirements.
●Only connect the power supply unit to a power source that is protected by a 16 A
circuit breaker (branch protection).
●Ensure that you can disconnect the power supply unit from the power source at
any time. Pull the power plug to disconnect the chamber. The power plug must be
easily accessible.
●Install an easily accessible panic button (power-off switch, not included in the deliv-
ery) for interrupting power supply to the chamber.
Operating the door
You can open and close the door by pressing a button while standing next to the cham-
ber. Also, you can operate the door remotely. In either case, ensure that nobody has
their fingers on the guide rails of the door or between the door and door frame. Estab-
lish safety rules as the following:
●During manual door operation, only the person pressing the button is allowed in the
restricted area. After pressing the button, the person steps back from the chamber.
●During remote door operation, nobody is allowed in the restricted area.
●During operation, hands are kept out of the chamber, except for exchanging a
DUT. During DUT exchange, nobody is allowed to operate the door.
Use the chamber as it is designed. Never tamper with its safety installations.
For detailed instructions, see Chapter 7.3, "Operating the Door", on page 44.
Maintenance
Carry out the maintenance tasks as required. You thus ensure flawless functionality of
the chamber and, in consequence, the safety of everyone working with the chamber.
For detailed instructions, see Chapter 9, "Inspection and Maintenance", on page 55.
Cleaning
See Chapter 9.4.3, "Cleaning the Chamber", on page 57 and Chapter 9.4.4, "Clean-
ing the Gasket", on page 58.

Emergencies
R&S®TS7124AS
15Instructions Handbook 1179.2948.02 ─ 01
3 Emergencies
Possible emergencies can result from a failure of the soft-close mechanism that stops
the door, if an obstacle prevents closing, see Automatic Emergency Deactivation.
But if the soft-close mechanism fails and you have your hands in the way of the closing
door, your hands can get caught between the door and the chamber's frame. In this
case, use the Emergency Stop.
3.1 Emergency Stop
To stop the chamber's door quickly at any time, interrupt the electric power supply.
To interrupt the electric power supply
1. Hit the panic button that switches power off.
See "Prerequisites for power connection" on page 36.
2. If no panic button is installed:
● Pull the power supply unit out of the grid power socket.
● Or pull the DC plug out of its socket on the rear side of the chamber.
See Figure 7-1.
Interrupting the electric power supply has the following effects:
●The door movement stops immediately.
●The light in the Push-Button Switch Unit (if installed) is off, independent of the
door's state.
Also, the status LED next to the door is off.
●The pneumatic system is depressurized and the door is left forceless. You can
push it open or close manually against a merely frictional resistance.
To reactivate the chamber, proceed as described in Chapter 7.1, "Activating the Cham-
ber", on page 42.
3.2 Automatic Emergency Deactivation
During normal operation, the door closes tightly with high force to provide sufficient
shielding effectiveness. To prevent injury due to this forced closing, the door's soft-
close mechanism moves with a lower force until it is almost closed: maximum 8 mm
gap remaining. The door mechanism switches to high force to close the final 8 mm gap
only if no obstacle stops this low-force closing.
Automatic Emergency Deactivation

Emergencies
R&S®TS7124AS
16Instructions Handbook 1179.2948.02 ─ 01
3.2.1 Automatic Emergency Deactivation Due to Timeout
If the door does not open or close within the TIMEOUT period, the control system
switches to ERROR mode and automatically depressurizes the pneumatic system, leav-
ing the door forceless. This deactivation prevents a situation in which the operator's
hands are caught between the chamber and the door and the operator cannot reach
for the push-button switch unit.
Typically, the following reasons can prevent the door from opening or closing within the
timeout period:
●If the door speed is set too low, adjust it to match the timeout value; see Chap-
ter 6.8, "Adjusting the Door Speed", on page 40.
●If the TIMEOUT value is set too low, adjust it to match the door speed; see
TIMEOUT:<seconds> on page 53.
●If an obstacle is in the door's way, proceed as below:
To reactivate the chamber
1. Remove any obstacle out of the door's way.
2. Disconnect the 24 V DC power supply unit from the chamber.
3. Reactivate the chamber as described in Chapter 7.1, "Activating the Chamber",
on page 42.
You can verify proper functioning of the door's soft-close mechanism as described in
Chapter 6.6, "Testing Safety Systems", on page 37.
