ENGLISH
1. GÉNÉRAL
Assembly and installation should only be carried out by qualified per-
sonnel.
1.1 Application
The pump control is designed for fluid level control. It controls and
monitors one (YN3112) or two (YN 3212) pumps with a power input of
up to 4 kW.
For use in potentially explosive areas, the applicable regulations
must be followed.
The switchgear series YN3000 is not explosion-proof and may only be
used outside potentially explosive areas.

• Frequency : 50/60 Hz
• Control voltage : 230 V AC
• Max. connected power : P2
≤
4 Kw
• Current consumption range : 0.3 -12,0A (M) / 0.3-10A (T4)
• Protection : IP 65
• Temperature range : from -20 °C to +60 °C
• Alarm contact : contact load
250 V, 1 A
2. SAFETY
These instructions contain important information which must be follo-
wed when installing and operating the device. It is therefore impera-
tive that they be read by both the installer and the operator before
the device is installed or operated. Both the general safety points in
this section and the more specific safety points in the following sec-
tions should be noted.
2.1 Instruction symbols used in this operating manual
Safety precautions in these operating instructions which, if not
followed, could cause personal injury.
Safety precautions warning of danger due to electricity.
Used to indicate that by ignoring the relevant safe-
ty instructions, damage could be caused to the
machinery and its functions.
2.2 Staff training
The personnel installing the pump must have the appropriate qualifi-
cations for this work.
2.3 Risks incurred by failure to comply with the safety precautions
Failure to comply with the safety precautions could result in personal
injury or damage to the installation. Failure to comply with the safety
precautions could also invalidate any claim for damages.
In particular, failure to comply with these safety precautions could
give rise, for example, to the following risks :
- The failure of important functions of the installation.
- Personal injury due to electrical, mechanical and bacteriological
causes.
2.4 Safety considerations for the operator
The relevant accident precaution regulations must be observed.
Potential dangers caused by electrical energy must be excluded.
2.5 Safety considerations for inspection and assembly
The operator is responsible for ensuring that inspection and assembly
are carried out by authorised and qualified personnel who have stu-
died the operating instructions closely.
Work on the installation should only be carried out after the machine
has been switched off.
2.6 Unauthorised modification and manufacture of spare parts
Alterations to the control box may only be carried out with the
Salmson consent. The use of original spare parts and accessories
authorised by the manufacturer will ensure safety. The use of any
other parts may invalidate claims invoking the liability of Pompes
Salmson for any consequences.
2.7 Improper use
The operating safety of the equipment delivered is only guaranteed
for proper usage as detailed in Section 1 of the operating instructions.
Under no circumstances should the limit values given in the data
sheet be exceeded.
3. TRANSPORT AND INTERIM STORAGE
When receiving the material, check that there has been no damage
during the transport. If any defect has been stated, take the required
steps with the carrier within the allowed time.
The switchgear must be protected against moistu-
re and mechanical damage as a result of shocks
or impacts. It may not be exposed to temperatures outside the range
-20°C to +60°C.
4. PRODUCTS AND ACCESSORIES
4.1 Description (See FIG. 1 - 2)
FIG. 1 - Float switch
FIG. 2 - Level sensor IPAE (0-1 mCW)
Swichting levels :
A - Base load OFF : determines the switch-off point of the first pump.
B - Base load ON : determines the switch-on point of the first pump.
C - Peak load OFF : determines the switch-off point of the second
pump.
D - Peak load ON : determines the switch-on point of the second
pump.
(the value should be equal to or greater than base load OFF).
E - Maximum water level : a Maximum Water Level alarm is genera-
ted when this value is exceeded.
• The water level is recorded electrically by means of float switches
( See FIG. 1 ).
Up to 4 float switches can be connected. The switch-on and switch-
off points are determined by the arrangement of the float switches in
the shaft. Also fewer float switches can be used. The contacts for
unassigned level connections must remain free.
• The water level is recorded electrically by means of an external
level sensor (0-1 mCW) ( See FIG. 2 ) (4-20 mA, two-wire technique).
Explosion protection only via safety barrier
(accessory).
The external sensor converts the level into an electrical signal (4-20 mA).
The electronic control system YN3000 allows automatic operation of
the system.
The control system basically consists of a microcontroller unit (CPU)
for the control, monitoring, recording and setting of all operating
sequences.
The pumps are switched via contactors. A built-in Electronic
Overcurrent Circuit Breaker protects the pump against overloading.
