Two-hand safety operator panel

Design:
Compact cast aluminium housing with control elements, cable and coupling plug.

Application:
The two-handed safety operating panel may be used only in combination with the pump units from Andreas Maier GmbH & Co. KG. It is suitable for the units with the following order numbers: 327635, 325969 or 326041.
The two-handed safety operating panel controls fixtures (cylinders, etc.) on which hazardous extension and retraction movements (strokes ≥ 4 mm) can occur.
The following fluidic system requirements must be met for the operating panel function:
- 4/3-way valve with hermetically sealed zero position.
Alternatively, the combination of a 4/3-way valve, in which A, B and T are connected and P locked in the zero position, with at least one controlled check valve for the dangerous consumer line, or a controlled twin check valve, is possible.
- Pressure switch in channels A and B
To convert an existing unit to two-handed operation, please contact Andreas Maier GmbH & Co. KG.

Mounting:
Plug the cable with the plug into the remote control connector of the pump unit. Set the pressure switch to operate at about 75% of the pressure in the clamping circuit. The M5 threads can be used for external fastening from below.

Operation:
Key switch for turning on and switching to zero position and coupling position. Rotary switch for selecting the following functions - clamping, unclamping and zero position. Two-hand switch for initiating movements. Stop switch for fast switch-off in case of danger. Indicator lights signal the control status.

General:
Re-clamping required following an electrical voltage outage and after the power supply is restored. With pump unit no. 6906, the solenoid on the directional valve remains energised after self-locking.

Note:
Each user of the two-handed safety control panel must determine the necessary performance level of the respective safety function by his own risk assessment and must ensure that this is also complied with.
