7. Reset to default values (factory setting)
A1.HI, A2.HI: upper limit value
A1.Lo, A2.Lo: lower limit value
For the range functions A1.FU, A2.FU = rAnG or Out.r this value defines between „-1999...9999"
the upper/lower limit of the window function. This parameter is not displayed for other operating
principles. The operating principle can switch between switching point 1 and 2.
A1.oF, A2.oF: Dropout delay
Here, for the limit values, a delayed switch-off of 0-5999 s are specified. The time value is not
stored permanently and is reset by a device startup. In addition, the alarm status is determined
directly when the device is started, without taking the set delay into account.
A1.on, A2.on: Pick-up delay
Here, a delayed switch-on of 0-5999 s can be specified for the limit values. The time value is not
stored permanently and is reset by a device start. In addition, the alarm status is determined
directly when the device is started, without taking the set delay into account.
6.4. Safety parameters for locking/unlocking the parameterization
Parameter
CodE
run
CodE: Assignment of an individual numerical code (4-digit number combination, freely
assignable). If this code is assigned (0000 factory setting), all parameters are locked for the
operator if LOC is then selected in the run menu item. By pressing [P] in operating mode for
approx. 3 seconds, the display shows the message CodE. The code must be entered before
each parameterization attempt until under run programming with ULoC is unlocked again.
run: Activation / deactivation of the programming lock
Here, [▲] [▼] can be used to switch between deactivated key lock ULOC (factory setting) and
activated key lock LOC be selected. Was LOC selected, the keyboard is locked. To return to the
menu level, [P] must be pressed for 3 seconds in operating mode. The now appearing CodE
(factory setting 0000) is set with [▲] [▼] and [P] entered and unlocks the keyboard. An incorrect
entry is displayed with FAIL.
In LOC-mode, the display cannot be reset, which is to additionally secure the regular operation.
7. Reset to Default values (factory setting)
To set the device to a defined basic state, it is possible to perform a reset to the default values.
For this purpose, the following procedure shall be applied:
Switch off the voltage supply of the device. Press the [P] key and switch on the power supply
again while holding down the [P] key. Press the [P] key until "----" appears in the display.
Resetting loads the default values and uses them for further operation. The device is now reset to
the delivery state.
CAUTION! All application-specific data will be lost!
