Reference Point And Mechanical Stops; 5-6.3 Setting The Upper Mechanical Stopper; 5-6.1 Setting The Reference Point; 5-6.2 Setting The Lower Mechanical Stopper - Electron E-ROBOT+3 Series User Manual

5.6. Reference point and mechanical stops

The reference point serves as starting point for the reciprocator control unit for calculating the upper and
lower reversing point and the maximum stroke.
By switching on the axis control unit, the reciprocator travels automatically to the reference point (proximity
switch). The reciprocator control units are programmed in such a way that the reference point is
always located 50 mm above the reversing point.
For transport reasons, the E-ROBOT+3 Z Reciprocator is delivered with the rubber buffer and the carriage
in lowest position.
WARNING:
Incorrect setting of the upper and lower stroke limits can cause damages to the
reciprocator, to the booth and/or to the applicators!
5.6.1. Setting the reference point
1.Move the stop plate with rubber buffer and proximity switch to the desired position and fasten it
2. Set the response gap of the proximity switch to approx. 2 mm
3. Consider the lower edge of the gun slot!
WARNING:
In order to avoid damages to the booth or the gun holders, the reference point must be checked
before the first start-up and if necessary, reset!
It must be noted that the axes in reference travel moves up to 25 mm below the control's zero
point, therefore the mechanical stop must be set in accordance to the gun slots!
The position of the upper and the lower stop plate is set by a Electron service engineer
when the reciprocator is assembled.
WARNING:
The reference point must be referenced before each start-up (at each switching on, after an
interruption of the power supply etc.)!
5.6.2. Setting the lower mechanical stop
WARNING:
The setting of the lower mechanical stop must take place without load and the reciprocator
must be disconnected from mains!
Procedure:
1. Let the Z carriage sink down until the powder gun holder is
approximately 50 mm above edge of the gun slot
2. Remove the boarding/side panels
3. Loosen the screws and move the lower stop plate up to the Z carriage
4. Tighten the screws
5. Refit the boarding/side panels
5.6.3. Setting the upper mechanical stop
WARNING:
The setting of the upper mechanical stop must take place without load and the reciprocator
must be disconnected from mains!
In order to set the upper mechanical stop, the stop position hast to be measured -
for this reason, consider the maximum height of the booth gun slots!
WARNING:
An incorrect (too high) set stroke limit can lead to damage to the reciprocator and/or the booth!
Procedure:
1. Remove the boarding/side panels
2. Loosen the screws and move the upper stop plate up to the measured position
3. Tighten the screws
4. Refit the boarding/side panels
WARNING:
After the adjustment of the mechanical stops, the system parameter for the upper stop must be
checked on the reciprocator control unit!
The value must not be larger than the maximum stroke possible between the stops!
