washing machine pressure switch

 

The pressure switch is a water level sensor used to control water level in applicances.

Additional functions allow protection of the heating element and against overflow.

Used in conjunction with a suitable designed air-trap,the device switches when the water level reaches the desired level.

The pressure switches are available with up to three levels(changeover contacts)plus optional heating element protection and overflow prevention contacts.

Trip and reset levels are calibrated according to customer specification.

General Description:

 

The type of 760 pressure switch consist of a moving diaphragm and disc which activate a changeover contact (snap action).

The contact  can be calibrated to trip and reset at the desired pressure levels.

The main contact may also close a secondary creep aciton contact in  series when it travels beyond the trip position (flood protection contact).

The main contact may also have a saftey" resetting even if the contacts have welded on the trip side"

The terminals are arranged to accept a 12.5 mm pitch connector, alternatively rast 5 or rast 2.5 .

 

Applications:

The main application is to control the level of water i applicances. May also provide flood protection and heater protection.

 

Mechnaical:

Available with lateral spout , angular position as specified by customer. or with axial spout.

On the lateral sport version , the cap can have an integral clip for snap-inmounting.

The mounting position must be indicated on the customer's drawing as it has an influence on calibration.

 

Mounting:

The pressure switch may be snap-mounted onto a steel or plastic panel or using a bracket and 3.5x11 mm self-tapping screws.

 

SINGLE LEVEL PRESSURE SWITCH TYPE 760

 

 

PRESSURE SWITCH USE AND PRECAUTIONS:

These use and precautions are intended to prevent damage or injury. The pressure switch is an electrical switch for pressure level sensing. The intended application of the pressure switch must be according to EIBi drawing. Any use under different condition must be previously approved by EIbi. For any additional information please refer to:

 

Packing:

1.Handle packaging with care.

2.Always keep the packaging close.

3.Do not store pressure switch in environment polluted by dust, dirt or chemical.

4.Avoid direct exposure to atmospheric events like rain,direct sun, extrem temperatures. etc.

5. Avoid store near heaters or fans.

6.We suggest not storing the pressure switch longer than 6 months.

 

Handling:

1.Handle with care; avoid bending the tabs, avoid touching them with fingers, causing shocks, or impacts that could result in breaking and /or permanent deformation etc.

2.Do not use pressure switch that have fallen from more than 30cm on to a hard surface.

3.We suggest to always wear gloves during handling and assembly.

 

Assembling:

1. Do not use lubricant paste or solvent on the tabs or on hose during any operation.

2. Do not  attempt to open , modify, tamper or subsitute any part of the pressure switch.

We do not take any responsibility for pressure sensors that have been tampered with.

3.Do not touch internal parts of the pressure switch.

4.Do not insert any parts into the hose.

 

Harness:

1. Connectors inserted on to the tabs must be installed in such way as to not bend the tabs and must be done in a parallel direction to the  tabs axis.

2. Do not bend the tabs or use a short wiring that may bend them.

 

Installation:

 

1.Avoid using sealing compound that could clog the hose.

2. Do not use the snap fit to push or pull the pressure switch. Do not wrench on the snap fit or on the pressure switch body.

3.Do not use the lubricant or solvent on tabs or on hose.

4. Avoid installing the switch in a different position in the appliance without EIbi approval.
