5.2.1 Switching functions

The switching outputs can be configured via the switching functions. The switching logic of the switching outputs can be configured as normally open (NO) or normally closed (NC). The switching mode of the switching outputs can be set as threshold value or window comparator.

14 Festo — OVEM — 2019-03g

Product overview

With active air saving function, the switching mode is set as the threshold value comparator by switching output A.

Threshold value comparator Normally open (NO) Normally closed (NC)

Switching function: – 1 switching point (SP1) TEACH mode1): – 2 teach points (TP1, TP2) – SP1 = ½ (TP1+TP2)

Product overview

5.2.2 Valve controller

Control of the ejector pulse

– Auto-drop function (except for OVEM-...-1PD)

The ejector pulse is generated after the “Suction” signal change. The duration of the ejector pulse can be setè 9.1 Setting the ejector pulse duration.

– Signal-controlled ejector pulse (only OVEM-...-1PD)

The ejector pulse is generated via a control signal at the digital switching input (ejection) DI2. The ejector pulse can also be used to blow dust off the workpiece surface. The duration of the ejector pulse can be set via the duration of the control signal at the digital switching input (ejector) DI2. Depending on the input signal, the vacuum solenoid valve or the ejector pulse solenoid valve is controlled.

switching point SP1

Fig. 4 Mode of operation of the air saving function

If the pressure value has reached switching point SP1 2, vacuum generation is deactivated. An internal check valve prevents reduction of the vacuum. Vacuum can still be reduced slowly due to leakage in the overall system (e.g.due to rough workpiece surfaces). To reduce energy consumption, vacuum generation is not switched on until it falls below the lower threshold value 3. The air saving function is activated in the factory. If air-permeable workpieces are transported, the vacuum is reduced more quickly, which would cause the vacuum generation to switch unnecessarily often. In this case, it makes sense to deactivate the air saving function è 9.14 Switching air saving function on or off.

5.2.4 Optimisation of the transport time

The transport time can be optimised for variants with 2 switching outputs (OVEM-...-2P/-2N/-PU/-PI) by using switching output Out B. The vacuum required for the transport is controlled by switching output Out A. To optimise the transport time, the workpiece can e.g. be gripped by the usable vacuum while the vacuum is building up. The minimum usable vacuum required is monitored by switching output Out B.

5.2.5 Monitoring and diagnostics

The vacuum generator has monitoring functions that enable early detection of malfunctions or faults during operation. – Monitoring of process parameters (pressure value at the vacuum connection, switching points,

switching outputs and switching inputs, evacuation time tE, air supply time tB and critical limits)

– Diagnostic messages è 11.1 Diagnostic levels – Fault detection è 11 Error messages and fault clearance

18 Festo — OVEM — 2019-03g

Product overview

The diagnostic messages are shown in the display. Switching output Out B can also be set as a diagnostic message channel (dI 1 or dI 2) for variants with 2 switching outputs (OVEM-...-2P/-2N)è 9.4 Set diagnostic message channel. The monitoring functions are activated at the factory (except for monitoring of the evacuation and air supply times). The time monitoring can be activated through setting of the critical limits for evacuation time and air supply timeè 9.7 Setting critical limits for the evacuation and air supply times.

5.2.6 Measured variables

Pressure value (vacuum)

The pressure value (vacuum) is continuously measured between the vacuum connection and filter.

With the OVEM-...-20/30-C the pressure value (vacuum) is continuously monitored between the filter and the check valve.

The minimum and maximum measured pressure values are saved. If the operating voltage of the vacuum suction nozzle is switched off, the values are lost.

Cycle time

A cycle covers the time from the start of evacuation through ejection to the start of the new evacuation.

Evacuation time and air supply time

The evacuation time tE is measured from the start of evacuation until switching point SP1 of the switching output is reached. The air supply time tB is measured from the start of air supply to the time at which the pressure value (vacuum) falls below −50mbar.

5.2.7 Teach function (teach-in)

The Teach function enables configuration of the switching points and time monitoring during run time.

Static teach-in

Depending on the Teach command, one switching point (SP) or 2 switching points (SP1, SP2) are determined from 2 teach-in points. The switching points are determined statically, that is, the measurement value remains constant during the entire teach-in procedure. The air save function is deactivated for the duration of the teach-in procedure.

Dynamic teach-in

Setpoint values are calculated within the teach-in procedure from a time period. The procedure is used to determine evacuation and air supply times. After the start of the teach-in, time tE and tB are measured at every cycle. The times are averaged over multiple cycle times. At the end of the teach-in, a function reserve of 100%is added to the averaged values.

An unfavourable mounting position can impair the function of the product.

• Install the vacuum generator so condensation from the compressed air lines cannot accumulate in the device.

• Install the vacuum generator so that it cannot be heated above the maximum permissible operating temperature (plan for possible convection).

• Install the vacuum generator so that the exhaust can flow without hindrance.

• For the electrical power supply, use only PELV circuits in accordance with IEC 60204-1/EN 60204-1 (Protective Extra-Low Voltage, PELV).

• Observe the general requirements of IEC 60204-1/EN60204-1 for PELV circuits.

• Only use voltage sources that ensure a reliable electric separation from the mains network in accordance with IEC 60204-1/EN 60204-1.

• Connect the vacuum generator to the electrical connection. – 5-pin plug, M12x1 – Maximum tightening torque plug connector M12: 0.5Nm – Maximum permissible cable length: 20m

Commissioning

8 Commissioning

Commissioning by qualified personnel.

8.1 Commissioning vacuum generator

At initial commissioning, the vacuum generator is placed in operation with the factory settings è Tab. 21 Factory settings.

Requirement

Vacuum generator is fully mounted and connected chapter è 6 Assembly.

Checking operating conditions

• Check operating conditions and limit values è 14 Technical data.

Commissioning vacuum generator OVEM-...-OE

1. Apply operating pressure to supply port (1).

Negative pressure is generated at the vacuum connection (2).

2. Switch on the operating voltage.

The current pressure is displayed and the vacuum generator is ready for operation.

Commissioning vacuum generator OVEM-...-CE

1. Apply operating pressure to supply port (1).

2. Switch on the operating voltage.

3. Activate suction: apply input signal to pin 5.

Negative pressure is generated at the vacuum connection (2). The current pressure is dis-

played and the vacuum generator is ready for operation. Changing the operating pressure changes the power of the negative pressure at the vacuum connection. This adjusts the vacuum at the suction gripper. Functions and parameters can be specified: – manually at the device – by teach-in

8.2 Set the intensity of the ejector pulse

Fig. 14

Operation and use

Requirement

– Vacuum generator is in operation

Processing

1. Screw in the flow control screw completely The channel for the ejector pulse is closed. An ejector pulse is not generated.

2. Switch on vacuum generation. Negative pressure is generated at the vacuum connection (2).

3. Switch off vacuum generation.

4. Unscrew flow control screw slightly. An automatic ejector pulse is generated. If an automatic ejector pulse is not generated, oper-

ate the mechanical manual override of the ejector pulse solenoid valve.

5. Screw the flow control screw out or in to adjust the ejector pulse to the required intensity.

Setting the ejector pulse duration è 9.1 Setting the ejector pulse duration

5. Press and hold the EDIT button for 3 seconds. RUN mode is active.

When large suction grippers are used, a vacuum independent of the device may be built up for physical reasons. The result is that the workpiece may not be released from the suction gripper, even if the ejector pulse is set to a sufficiently long duration.
