2.2 Intended use of the TTD

The TTD is used as day tank to supply plants and equipment with fuel or lubricating oil. The TTD is also referred to as supply tank. It can be installed at

indoor sites or in an equipment container. The area on which the tank is installed should be level and have sufﬁcient load bearing capacity. The tank

should only be installed in areas which are not exposed to additional hazards or requirements. If the tank is used under special conditions, all applicable

requirements should be observed.

The cube shape of the TTD ensures maximum utilization of available space. The tank is set up close by the equipment which it supplies so that the small

external pump or the pump integrated in the tank unit can pump the liquid. To facilitate this, the connected piping should not include any considerable

height differences or bends. The TTD is manufactured according to the general inspectorate approval No. Z-38.12-23.

CAUTION Move the TTD only when it is empty and clean.

CAUTION When installing the TTD under special conditions, e.g. in a potentially explosive zone, all applicable requirements should be

observed.

man’s principle

The following connections are provided on the TTD:

1. Roof side: Six connecting sleeves 2´´ for optional installation of level

sensor, overﬁll guard, machine return pipe, ﬁlling by pump, ﬁlling from tank

truck, and bleeding. Located at the center is an NBR rupture disk which

protects the tank from overpressure. If the rupture disk is removed, the

opening can be used as hand hole or for inspection.

2. Front side: A 2” overﬂow sleeve for connection of an overﬂow pipe

back to the storage tank is located on the right, centrally relative to the

top edge 2”. If no overﬂow pipe is installed, the connecting sleeve should

be closed by a dummy plug. The overﬁll tube is a reasonably priced alter-

native to the overﬁll guard, for which the storage tank should not be more

than ﬁve meters away from the day tank and not placed lower than the

outline of the day tank.

If the day tank is used without a storage tank, an approved safety device

protecting against overﬁlling is prescribed for capacities of 1,000 liters or

more. The same requirement also applies to smaller tanks which are not

ﬁlled from tank truck via dispensing nozzle.

The static vacuum leakage indicator is suitable for tank systems without

permanent power supply. It consists of an impact resistant stainless steel

housing with capsule pressure gauge and a ﬁlling of glycerol.The alarm is

indicated visibly by pointer. The vacuum is produced by an external pump

in the space monitored for leakage and enclosed. If the vacuum drops, the

alarm is indicated by the pointer entering the red range.

The vacuum leakage indicator should be inspected visual

• regularly during operation and, in particular, after

• every transport

• every change of another location

• every initial start-up

• every restart

• every temporary shut-down

• in accordance with control procedures during operation.

Stop operation of the equipment if the pointer enters the red range of the

scale. The static vacuum leakage indicator is marketed general inspecto-

rate certiﬁcate No. Z-65.22-158.

Level sensors sense the level of a liquid inside a tank. There are different

types of level sensors:

a) a switching system with level switches, and

b) an electronic measuring system with encoders.

The signals of level switches can be used directly for automatic control,

regulation or signaling.

In electronic measuring systems, the signal from the encoder is converted

in appropriate switching signals by the associated evaluation logic.

2.5.6 The bleeding adapter with hood

The 2´´bleeding tube is installed in a 2´´connecting sleeve in the tank roof.

If the tank is ﬁlled from a tank truck by the tank truck connection, the bleeding

line should at least be at the same height above the tank roof as the socket for

ﬁlling from tank truck.

Tanks installed below ground level (for example in the basement of a building)

should have the bleeding adapter installed at least up to 500 mm above the

connection for ﬁlling from tank trucks and 500 mm above ground level. The

bleeding pipe should not end inside an enclosed room.

Exception: Above-ground individual tank for Diesel fuel or fuel oil smaller than

1000 liters.

(min. DN 50)

The electric level switch (miniature alarm) control and signals exactly de-

ﬁned levels in the tank.When a 4-way cable gland is used, up to four level

switches can be installed in a tank.

The level switch does not need approval because it is only used as normal-

ly-open contact in tank systems, for example, for „pump on“ control (low

level contact) or „pump off“ (high level contact). Only approved overﬁll

guards are permitted for „overﬁlling alarm switching point (max-max).

The level switch can also be used for simple detection of leaks.

The level switch is made of stainless steel and is equipped with a ﬂexible,

oil-resistant cable. The permitted temperature range of the cable is bet-

ween -5°C and +50°C. The 5-meter connecting cable is installed directly

If operating voltage (230 V, 50 Hz) is supplied and vacuum has built up,

the green lamp lights. The leakage indicator generates constant vacuum

(approximately -400 mbar) in the monitored space of the tank and sounds

an alarm if the vacuum drops (= pressure rises) (below about -340mbar).

The alarm is provided visually (red alarm lamp) and audibly and can be

sampled at a ﬂoating relay contact (1 switchover). The audible alarm can

be muted after breaking the seal under the „alarm sound“ toggle switch.

When the supply voltage fails, no alarm is triggered.The device is ready for

operation immediately after the power supply is restored.

A leak that may have developed in the meantime will be signaled.

A visual check of the leakage indicator is made

• every time the device is transported

• every time the device is moved to another site

• every initial start-up

• every restart

• every temporary shut-down.

The pump cannot produce more vacuum. Vacuum remaining in the moni-

tored space and the measuring line is consumed by the entry of more

liquid.

When the alarm threshold is obtained, visual and audible alarms are trig-

gered. Vacuum remaining when alarm is triggered is sufﬁcient to prevent

the entry of stored medium in the environment.

2.6.4 The electronic vacuum leakage indicator

Vacuum leakage indicator for monitoring double wall tanks. The leakage

indicator establishes and maintains vacuum in the monitored space of

the double wall tank. If a gas leak occurs, air or fumes is taken in the

monitored space and causes a vacuum drop.

Minor leaks are compensated by starting the pump. Major leaks cannot

be compensated by the pump because the pump capacity is insufﬁcient

for this. In this case, vacuum will be reduced further. When the vacuum

alarm threshold is obtained, visual and audible alarms are triggered.

If a liquid leakage occurs, stored medium or ground water will be taken

in the monitored space. Vacuum drops and the pump starts working to

restore the operating vacuum level.

After some time, stored medium or ground water will be taken in the

monitored space. The liquid barrier closes and separates the pump from

the monitored space.

The leakage indicator operates on 230 V, 50Hz

mains voltage. This voltage can cause extreme-

ly severe burn injuries. Contact with this voltage

can be fatal. Disconnect the supply voltage before

you open the leakage indicator or starting main-

tenance or repair work (switch off the fuse!).

15Krampitz Tanksystem GmbH - Operation and Installation Instructions TTD for Tank System - Issue 04/2011

Any tank that is intended for storing Diesel fuel or fuel oil and which has with the tank truck connection, except above-ground tanks containing not more

than 1,000 liters, which are ﬁlled by manual nozzle without permanently installed piping, must have an overﬁll guard which stops the ﬁlling procedure in

time when the permitted level is obtained or triggers an audible alarm.Tanks containing more than 1,000 liters and intended for storing Diesel fuel or fuel

oil, which are ﬁlled from road tank trucks or top-mounted tanks, must be equipped with a limit sensor which functions as safety device on tank trucks or

top-mounted tanks (also refer to TRbF 20 Article 9.3). Tanks for storage of other potentially water-contaminating liquids and ﬂammable substances, e.g.,

mineral oil, which are ﬁlled automatically, must be equipped with an approved overﬁll guard.The overﬁll guard should not be used as switching point for

actuating the replenishing device in normal operation.

NOTE The overﬁll guard must be approved for the storage medium.

NOTE Tanks must not be ﬁlled higher than the permitted maximum ﬁlling level.The permitted ﬁlling level depends on the medium

(coefﬁcient of cubic expansion; also refer to TRbF 20) and is limited to 95 % of the tank height of the TTD.

The limit sensor is a device which in coo-

peration with the safety device (evaluation

logic) on tank trucks prevents overﬁlling of

permanently installed tanks. Permanently in-

stalled tanks for storage of Diesel fuel or fuel

oil which are ﬁlled from tank trucks must have a limit sensor. Exception:

Tanks smaller than 1,000 liters ﬁlled by manual nozzle without perma-

nently installed pipe. The limit sensor should be adapted to the highest

permitted ﬁlling level of the tank. (Also refer to limit sensor installation

instructions).

2.6.6.2 The overﬁll guard with evaluation logic

The PTC termistor based level sensor of the approved overﬁll guard is in-

stalled in a 2” sleeve in the tank roof by means of a 2´´ x ¾´´ adapter (refer

to adapter). An approved overﬁll guard is required in any case if the tank

is ﬁlled by electric pump and permanently installed pipeline. The overﬁll

guard should be adapted to the highest permitted ﬁlling level of the tank.

The oil alarm sensor detects the different optical behavior of air and liquids.

It is placed at the lowest point of the monitored space. The integrated signal module

provides constant monitoring of the electric output signal of the sensor. When the system

is ready, the green lamp lights. If the sensor is exposed to air, the signal module sends

a go ahead signal: The green operating lamp lights, the red alarm lamp is off, the relay

drops out. When the sensor is immersed in oil, the signal module signals a leak (alarm):

The red alarm lamp and the audible alarm are triggered, the relay picks up. The audible

alarm can be muted by pressing the “Rest” button. Pressing the button activates the

audible alarm again.

If several sensors are connected to one evaluation logic, the sensors can be closed by

the number of blinking pulses of the yellow indicator lamp. The frequency of the blinking

pulses is about three seconds. No alarm is triggered if mains power fails. The device is

ready when mains power is restored. Any leak occurring during power outage will be in-

dicated. The green operating lamp shines as soon as the oil alarm is supplied with mains

voltage. The function of the alarm function can be simulated with the check button.

The oil alarm is an approved leakage warning device. It is installed in the sump space

of the day tank. Up to 5 sensors can be connected to one evaluation logic. The oil alarm

quickly detects leaks of substances dangerous to water according to VAwS. If a sensor

is immersed in liquid, the signal module identiﬁes the change of the sensor signal and

triggers a visible and an audible alarm and also operates the relay for the output unit.

The oil alarm consists of a signal module and up to ﬁve sensors.The signal module and the sensors are connected with each other by a 3-wire signal cable

of up to 10 meters length. The oil alarm sensor consists of an infrared transmitter and an infrared receiver attached at a certain distance to each other.

Both parts together form an optical barrier. If air is between the transmitter and the receiver, most of the infrared radiation emitted by the transmitter is

received. The system operates on the optical coupler principle. The signal module contains an impact resistant plastic housing indicators and controls as

well as the required electronic components for evaluating and converting the sensor signal into a digital output signal. The output signal is available as

ﬂoating relay contact (changeover contact).

3.1 Transport of the TTD

The KTD can be easily transported by fork lift or hand lift.

During transport, the relevant, currently valid safety regula-

tions must be observed and damages must be avoided.

In the event that the colour coat is damaged, corrosion

protection must be properly restored.

CAUTION

3. START-UP

The permit system for mounting the tank wall at a building site must be

obtained. The static strength of the wall (at least B15) must be proven

before installation. The day tank can be mounted by using two anchor

wall brackets with four corresponding types of fasteners. The wall bracket

(pos. 2) will be at the rear holes of the front walls (pos. 1) mounted with

the tank bolts M 10 (pos. 3).

After the day tank means including wall bracket with hoist on the wall is

positioned. Now it’s possible to drill holes in the wall, then can be the wall

anchor (corresponding to manual) ﬁxed. Now, the day tank with the wall

brackets on the wall or be attached to the wall anchor.

CAUTION The lifting of the tanks is to follow safety rules for appropriate and valid. There is danger of injury and damage to components.

CAUTION Rollover risk in cases of excessive movement by moving the construction.

3.4 First start-up

Before ﬁlling the TTD for the ﬁrst time, check that::

1. the tank is properly fastened and placed

2. the pipe connections are leak-tight and properly connected

3. the sensors are properly connected, such as the

a. level sensor b. over-ﬁll protection

c. oil warning probe (oil detector) d. limiting-value transmitter

4. the blind plugs are tightly connected

3.5 Operation sequence

• Check the position of the ball valves. The ball valves at the system ﬂow connection must be closed.

• Apply voltage. The voltage puts the sensors into operation.

• Bei Betankung mit anlageneigener Pumpe Stellung der Pumpenkugelhähne überprüfen.

CAUTION The over-ﬁll protection triggers an alarm during the ﬁrst seconds because the PTC thermistor of the level sensor

must heat up ﬁrst.

• Fillings by tank lorry:

1. When the ﬁlling level rises, the switching of the level switch points can be checked (if applicable, these are: MIN-MIN, MIN, MAX, MAX-MAX).

2. As soon as the limiting-value transmitter is wet, the ﬁlling is automatically interrupted. The ﬁlling via ﬁlling connection with a tank lorry is mandatory

for storage tanks with a capacity of more than 1,000 litres. Smaller daily tanks can be ﬁlled with the petrol pump nozzle with a dead man‘s switch

which automatically shuts off fuel delivery

• Fillings by system pump:

1. When the ﬁlling level rises, the switching of the level switch points can be checked (if applicable, these are: MIN-MIN, MIN, MAX, MAX-MAX).

2. As soon as the installed over-ﬁll protection is wet, the pump must be automatically switched off

• check pipe connections for leak-tightness

• ﬁlling level per level indicator to check again

• if necessary, open the ball valves at the system ﬂow connection

• The TTD is now ready to use

3.3 Setting up the TTD on feet / supporting

The KTD must only be placed on even and load-bearing ﬂoor space (minimum quality B 15 or equal). A stress analysis must be performed and presented.

Generally, storage tanks up to a maximum storage volume of 5,000 litres can be operated in a machine room.

The day tank can be positioned exactly over the injection pump of a motor with the stand column. For this will be the foots of the stand column connected

wit the head plate of the sub-carrier (bolts M 10).
