1. The unit may be used only i n the operating conditions and positions specified by the manufacturer. Unless otherwise agreed, the following applies to R&S products:

Pollution severity 2, overvoltage category 2, IP degree of protection 2X, altitude max. 2000 m.

The unit may be operated only from supply networks fused with max. 16 A.

2. For measurements in circuits with voltages V > 30 V, suitable measures should be taken to avoid any hazards.

(using, for example, appropriate measuring equipment, fusing, current limiting, electrical separation, insulation).

3. If the unit is to be permanently wired, the PE terminal of the unit must first be connected to the PE conductor on site before any other connections are made (installation and cabling of the unit to be performed only by qualified technical personnel).

4. For permanently installed units without built-in fuses, circuit breakers or similar protective devices, the supply circuit must be fused such as to provide suitable protection for the users and equipment.

5. Prior to switching on the unit, it must be ensured that the nominal voltage set on the unit matches the nominal voltage of the AC supply network.

If a diff erent voltage is to be set, the power fuse of the unit may have to be changed accordingly.

6. Units of protection class I with disconnectible AC supply cable and appliance connector may be operated only from a power socket with earthing contact and with the PE conductor connected.

7. It is not permissible to interrupt the PE conductor intentionally, neither in the incoming c able nor on the unit itself as this may cause the unit to become electrically hazardous.

Any extension lines or multiple socket outlets used must be checked for compliance with relevant safety standards at regular intervals.

8. If the unit has no power switch for disconnection

rms

from the AC s upply, the plug of the connecting cable is regarded as the disconnecting device. In such cases it must be ensured that the power plug is easily reachable and accessible at all times (length of connecting cable approx. 2 m). Functional or electronic switches are not suitable for providing disconnection from the AC supply.

If units without power switches are integrated in racks or systems, a disconnecting device must be provided at system level.

9. Applicable local or national safety regulations and rules for the prevention of accidents must be observed in all work performed.

Prior to performing any work on the unit or opening the unit, the latter must be disconnected from the supply network.

Any adjustments, replacements of parts, maintenance or repair may be carried out only by authorized R&S technical personnel.

Only original parts may be used for replacing parts relevant to safety (eg power switches, power transformers, fuses). A safety test must be performed after each replacement of parts relevant to safety.

(visual inspection, PE conductor test, insulationresistance, leakage-current measurement, functional test).

Chapter 2: Preparation for Operation

Preparation for operation

Placing the unit

The VOR/ILS Analyzer EVS200 can be operated in any position without reduction in its function. Even shocks during normal transportation or on mobile operation don’t reduce its function.

The unit works at ambient temperatures of -5 to +40°C.

Mains operation

Safety Rules

The VOR/ILS Analyzer EVS200 meets the safety rules in ag- reement with VDE 0411 and VDE 0804 of safety class I. In agreement with safety class I all mains circuitry must be insulated and the requirement is a good conductive and durable together and ground wire connection of all touchable, conductive parts of the unit which can directly be alive in case of a failure.

Mains connector (earthed plug) put only into a protective

contact socket. If there is a connector it must durable be

connected with a ground wire. The ground wire must not

be insulated.

Mains connection

Connect the VOR/ILS Analyzer EVS200 with the supplied power cord to the AC supply (87 to 265 VAC / 47 to 63 Hz or corresponding to the technical data).

If the unit shall be connected to another AC supply the

corresponding safety rules must be observed!

Operation

Switch On/switch Off the unit at mains supply

 With the mains switch at the rearside

switch the unit on or off.

 With the switch "POWER" at the front

side switch the unit on or "STANDBY".

On switch position "STANDBY" the installed battery (option) will be charged. Details see item "Battery Operation" (page 12).

Chapter 3: Operation

Switch On/switch Off the unit at VDC supply

When the unit is supplied from the installed battery (option) or through the external DC input it must be switched on or to "STANDBY" only with the Switch "POWER" at the frontside.

On external DC supply of the unit the installed battery

(option) will not be charged!

Switch on procedure

During the switch on procedure the VOR/ILS Analyzer EVS200 performs a selftest (BITE). The

tested functions are indicated with "OK". This test takes approx. 5 s. After that automatically it is switched over to the startup mode which was set in the setup.

Because of the displayed battery voltage (U BATT) it is possible to value the charging state of the installed battery (option).

ßßßß

Malfunctions of the BITE will be indicated by "FAIL". In that case the unit does not switch over

to the startup mode (see also item "Selftest").

0796.1800.02 E-8 11

VOR/ILS Analyzer EVS200

Selftest (BITE)

Chapter 3: Operation

The selftest checks:

 all operating voltages,  host processor,  memory,  DSP processor.

In case of an error the determined functional unit will be indicated with a "FAIL". If the internal operating voltages totally fail or if they deviate extraordinary from the tolerances a selftest cannot be carried out.

Error:

In case of an error the unit generally should be

switched off and after a few seconds it schould be

switched on again. If the error message is displayed

again it is recommended to send the unit to the

service, corresponding to Chapter 5 (Service).

Battery operation

The battery operation of the VOR/ILS Analyzer EVS200 is an optional component. It is always possible to retrofit the unit with this mode.

The unit automatically goes into battery operation when the external power supply (DC/AC) is switched or cut off. The battery operation is indicated on the display by the battery symbol (

) in each mode.

The operation time is >100 minutes (max. brightness) or >150 minutes (at average brightness) with a completely charged battery.

The charging state can be seen from the battery symbol on the display:

100% battery power approx. 75 to 25% battery power flashing symbol, approx. only 5 minutes operation is

ensured. Battery must be charged.

The battery will be charged on AC operation (as well during operation as on "STANDBY") and should take at least 12 hours (charging time).

After 4 to 5 years or when defect the battery must be

changed according to Chapter 5 "Service".
