Local Operation
5.3.1
Automatic/manual mode
The transmitter normally operates in automatic mode. Here, the relays are triggered by the
transmitter. In the manual mode, you can trigger the relays using the REL key. You can also
start the cleaning function with the REL key.
How to change the operating mode:
Pay attention to the following:
• The operating mode remains in effect even after a power failure.
• The manual mode has priority over all other automatic functions (Hold).
• Hardware locking is not possible in the manual mode.
• The manual settings are kept until they are actively reset.
• Error code E102 is signalled in manual mode.
1. The transmitter is in
Automatic mode
. The top LED beside the
AUTO key is lit.
2. Press the AUTO key. The bottom LED beside the AUTO key lights
up.
3. To enable the manual mode, enter the code
22
via the PLUS and
MINUS keys.
4. Select the relay or the function.
You can use the REL key to switch between the relays. The relay
selected and the switch status (ON/OFF) are displayed on the
second line of the display.
In manual mode, the measured value is displayed continuously
(e.g. for measured value monitoring for dosing functions).
5. Switch the relay. It is switched on with PLUS and switched off with
MINUS.
The relay remains in its switched state until it is switched over
again.
Three-point step controller
Closing the motor valve is assigned to relay 3, opening the motor
valve is assigned to relay 4. The PLUS button activates the selected
relay. The MINUS button deactivates the selected relay.
The transmitter controls that not both relays are activated at the
same time. Example: If relay 3 is activated and you try to activate
relay 4, then relay 3 will automatically be deactivated first.
6. Press the AUTO key to return to the measuring mode, i.e. to the
automatic mode. All the relays are triggered again by the
transmitter.
