3.1.3.3 Analysis of working order

Depending on the relevant country, there may be different national
regulations for determining the serviceability. According to TRGI,
the degree of serviceability is categorized as follows:

Leakage rate of gas < 1.0 l/h

unrestricted serviceability (result WO)

=> Device can continue to be operated

14

Leakage rate of gas ≥ 1.0 l/h and < 5.0 l/h

reduced serviceability (result LWO)

=> Proper working order must be established within 4 weeks

Leakage rate of gas ≥ 5.0 l/h

no serviceability (result NWO)

=> Device must be decommissioned immediately

3.1.4 Main test

Main test are leak tests which are used to detect even the small­est leaks. For this, the pipes are checked with all ttings – but

without gas equipment and corresponding controllers and safety

instruments. The gas meter can be included in the test.

Depending on the relevant country, there may be different na­tional regulations with respect to main tests. According to TRGI,
the following requirements have to be met:

z The minimum test duration is 10 minutes.

z During the test, the pressure must not decrease.

3.1.7 Start measurement/Stop measurement/Store

Measurements must always be started. Starting a measurement

is explained separately for each testing mode in the section title
Performing measurements.

At the end of the measuring period the measurement is auto­matically saved. A consecutively increasing number is assigned
to every measurement. It is possible to store max.122 measure-
ments. If all memory locations are assigned, the instrument starts
to overwrite the oldest measurements (FIFO memory [“First In,

First Out”]).

Simplied method for starting a measurement

Starting a measurement can be simplied, provided that the ap­plied pressure is greater than 5 mbar.

z Press the key and release it quickly. The measurement

starts.

If the described condition is not complied with, pressing the key

4 Charging and battery operation

4 Charging and battery operation

The instrument can be operated with two different types of batteries:

z Nickel metal hydride accumulators (rechargeable)

z Alkaline batteries (non-rechargeable)

Prescribed type: AA cells

Recommended manufacturers: Sanyo, Varta or Duracell

To ensure that the time required for recharging and of the remain-

ing operating time is indicated correctly, the following settings

need to be modied in the extended settings:

z Accu type (Info menu – Hardware – Battery)

z Capacity of the used accumulator types

(Info menu – Hardware – Accu capacity).

As default, the instrument is delivered with nickel metal hydride
accumulators. The corresponding settings are stored.

4.1 Operation with rechargeable nickel metal hydride accumulators (NiMH)

The accumulators are recharged
by the docking station HG4
which is included in the scope
of delivery.

This station can either be used

in the workshop or in the com­pany car.

36

4 Charging and battery operation

CAUTION!

To ensure trouble-free operation, the following in­structions have to be taken into account:

z The docking station must not be connected di-

rectly to the 24 V onboard power supply of the
vehicle. This voltage is too high for charging.

z The accumulator should roughly have ambient

temperature for recharging.

z Short usage times and long periods without using

the instrument can reduce the available accumu­lator capacity (memory effect).

Optional connections of the docking station:

z AC/DC adapter M4 for 100 – 240 V~

z Vehicle cable M4 12 V= mounting

z Vehicle cable M4 12 V= mobile

z Vehicle cable M4 24 V= mobile

Note:

You can connect up to three docking stations to a

single 100 – 240 V ~ power supply unit. If four or

more docking stations are connected, the charging
voltage is too low. In this case, an error message
appears on the display.

Charging procedure:

z Switch off the instrument and put it into the docking station.

The time required for a complete recharging cycle is indicated.

If the accumulators are completely recharged, the instrument
switches automatically to charge retention.

It can remain in the docking station until the next use.

After recharging the instrument for min. 12 hours (depending

on the accumulator capacity), it is ready to be used for at least

20 hours.

37

4 Charging and battery operation

Note:

If the instrument is switched off and kept outside
the docking station, the nickel metal hydride accu-

mulators start to discharge. After max. 30 days the

accumulators are completely discharged.

To retain the accumulator capacity, it is required to

completely discharge the instrument regularly (e. g.
once a month) before recharging it.

Discharging procedure:

z Switch on the instrument and put it into the docking station.

z The accumulators are completely discharged. After the dis-

charging procedure, the instrument automatically changes to
recharging.

A complete recharge/discharge cycle takes approx. 32 hours
(20 hours for discharging + 12 hours for recharging).

Note:

If you replace alkaline batteries by nickel metal hy­dride accumulators, the indicated operating hours
may not be correct. In this case, the instrument
must be switched on and put into the docking sta-

tion so that it can automatically perform a discharge/
recharge cycle. After that, the correct number of

operating hours will be indicated.

38

4 Charging and battery operation

4.2 Operation with non-rechargeable alkaline batteries

CAUTION!

A instrument operated with alkaline batteries cannot

be recharged in the docking station. If this instru­ment is put into the docking station, a corresponding
message appears on display.

The MiniLec 4 instrument can be operated with new alkaline
batteries for at least 20 hours.

Proceed as follows to replace batteries or accumulators:

z Loosen the two lower screws on the back panel of the instru-

ment using the supplied screwdriver.

z Open the battery compartment.

z Insert the new cells. Ensure that the batteries are properly in-

serted to maintain correct polarity.

z Close the battery compartment.

z Retighten the two lower screws on the back panel of the in-

strument.

Note:

If it takes more than 120 seconds to replace the

batteries, you need to re-enter date and time the

next time you switch on the instrument. All other

data remains stored.

5 Maintenance

5 Maintenance

The maintenance inspections for the device are divided into the
following areas:

z Functional test/inspection

z Check to ensure the indication accuracy and the leak-tightness

of the device

z Adjustment

z Maintenance and repair

5.1 Functional test/inspection

The functional test is performed by the user before commenc­ing work.

The following elements must be tested:

z External condition of the device

z Function of controls

z Battery charge status

z Zero point

5.2 Check to ensure the indication accuracy and leak-tightness of the device

The indication accuracy and the leak-tightness of the device must

be checked at least once a year.

SEWERIN recommends that these tests also be performed if any

irregularities occur during measuring or the measuring results
are inexplicable.

Checking the leak-tightness of the device means cheaking that
the MiniLec 4 itself is leak-tight. This check must not be confused

with the leak test (see section 3.1.4).

Both tests are carried out using a MiniLec 4 tester (see sec-

tion 7.6.2).

40

5.3 Adjustment

The device may only be adjusted by SEWERIN Service or an
approved technician/service company.

After adjustment a device which has been locked for inspection,
can be released again for use. This setting can be adjusted in

the Adjustment menu.

Note:
The adjustment settings can be reset in the Hard­ware menu under Reset.

5.4 Maintenance and repair

The device must only be serviced and repaired by SEWERIN

Service.

z Send the device to SEWERIN for repairs and for annual main-

tenance.

Note:

If there is a service agreement in place, the device
can be serviced by the mobile maintenance service.
