Wilo T 17 E3 Series - Operating Modes; Operation with Frequency Converter; Operation in an Explosive Atmosphere

en Product description
14 WILO SE 2019-01
Monitoring of vibration occurring due to operation
The pump can be equipped with a vibration sensor. The vibration sensor registers the
vibration that occurs during operation. An alarm or deactivation of the pump must be
effected via the pump control depending on the differing limit values.
NOTICE!The limit values are set on-site during commissioning and recorded in the
commissioning log!
4.3 Operating modes
Operating mode S1: Continuous duty
The pump can operate continuously at the rated load without exceeding the permiss-
ible temperature.
Operating mode: Non-immersed operation
The “non-immersed operation” operating mode describes the possibility of the motor
emerging during the drainage pumping sequence. This allows a further lowering of the
water level as far as the upper edge of the hydraulics.

Non-immersed operation allowed
Yes No Yes Yes No Yes No
Observe the following points during non-immersed operation:
ƒ Operating mode “non-immersed” indicated
The motor emerging in “non-immersed” operating mode is permissible.
ƒ Operating mode: “non-immersed” not indicated
If the motor is fitted with a temperature controller (2-circuit temperature monitor-
ing), emergence of the motor is permitted. Automatic reactivation can be initiated
after the motor has cooled down using the low temperature. The unit is forced to
deactivate with reactivation lock once the high-temperature has been reached.
CAUTION!To protect the motor winding from overheating, the motor must be
equipped with a temperature controller! If only one temperature limiter is in-
stalled, the motor must not emerge during operation.
ƒ Max. fluid and ambient temperature: The maximum ambient temperature corres-
ponds to the maximum fluid temperature shown on the rating plate.
CAUTION!The following applies to motor T12: During non-immersed operation,
the fluid temperature and ambient temperature must not exceed 30°C!
4.4 Operation with frequency con-
verter
Operation on the frequency converter is permitted. Refer to the appendix for the relev-
ant requirements!
4.5 Operation in an explosive atmo-
sphere
