13.1 Preset
The preset function permits automation of initialization of stacker crane and other rail-
bound vehicles during maintenance, commissioning or exchange. During initialization, the
desired output value is set in a defined position (initialization position) (preset value).
Depending on device version, there are the following options to perform a preset:
1) Static preset: Triggered via multifunctional input MF1 (versions DME5000-xx1, -xx3,
-xx4, -xx7)
Procedure:
 Set parameter "MF1/Function" to "Preset" and enter desired preset value.
 Move vehicle to initialization position and activate MF1, e.g. via proximity initiator,
photoelectric switch or switch.
 The DME5000 output value accordingly corresponds to the entered preset value at the
initialization position.
For version DME5000-xx1, observe that no negative measured values are generated
(negative values lead to measured value "0" in SSI-output).
For version DME5000-xx3, the preset can alternatively be set via a RS-422 command.
2) Static preset: Triggered via multifunctional input MF1
(version DME5000-xx2, when using the GSD module "Class 2", "4 byte in/out")
Procedure:
 Set GSD parameter "Preset mode" to "Preset mode".
 Set GSD parameter "MF1 Function" to "Preset" and enter desired preset value in GSD
parameter "Preset (steps)" (preset value unit corresponds to setting of the parameter
"Resolution").
 Move vehicle to initialization position and activate MF1, e.g. via proximity initiator,
photoelectric switch or switch.
 The DME5000 output value accordingly corresponds to the entered preset value at the
initialization position.
3) Dynamic programme-controlled preset: Triggered via PROFIBUS interface (version
DME5000-xx2, when using the GSD module "Class 2", "4 byte in/out")
Procedure:
 Set GSD parameter "Preset mode" to "Preset mode".
 Send desired preset value to the DME5000 via bit 0 … 24 of the output data (preset
value unit corresponds to setting of the parameter "Resolution").
 To trigger the preset, activate bit 31 in the output data; this bit can originate, e .g. with a
proximity initiator, photoelectric switch or switch at the initialization position.
 The DME5000 output value accordingly corresponds to the entered preset value at the
initialization position.
