Menu levels
Menu levels used in the electronics
• First function level: This level is used for selecting and setting the pump operating modes (manual, contact and analog) and starting.
• Second function level: This level is used for setting and viewing additional functions and setting the access code to protect the pump against unintentional adjustment.
• Service level: This level is used for setting the inputs and outputs, modifying the version of the Etron
Profi Electronics. It is possible to revert to the default settings.
Saving user settings
The pump settings are automatically saved approximately every 10 minutes. The settings remain after the power supply has been switched off.
General functions of the electronics
Deaeration and suction
If the [Start/Stop] button is pressed for more than one second, the pump switches to continuous operation.
The pump remains in continuous operation as long as the button is pressed (for example for suction or deaeration).
This occurs regardless of the selected operating mode.
Locking ‘run’
The pump can be locked to avoid manual stopping.
When activating the locking run function (service level), the pump starts running with the present settings and cannot be stopped by means of the [Start/Stop] button.
It is still possible to acknowledge error messages using the [Start/Stop] button.
Functions
Diaphragm Breakage Signal
As an option, the pump can be equipped with a sensor for Diaphragm Breakage Signal (MBS).
The electronics automatically detects whether a sensor is connected. The following appears in the display:

Remote switching
The pump can be switched off remotely, for example from a control room.
• If the pump is switched off remotely, it does not respond to any input signals or to operator input.
Exception: The pump can still be stopped and deaerated manually.
• "Stop" lights up in the display.
• The yellow LED lights up.
• When switched on remotely, the pump returns to the state it was in before it was switched off. If, for example, the pump was previously in the "Stop" mode, it returns to this mode once it is switched on.
Dosing controller
A dosing controller can be connected to the pump as an option.
The dosing controller monitors the dosing process and emits a pulse for each dosing stroke.
• During start-up or after 5 seconds of downtime, the electronics automatically detects whether a dosing controller is connected. The following appears in the display:

Functions
Error signal
The error signal is used for returning various error states to the control room.
Stroke signal and pre-empty signal
Depending on the relay setting, the contact output receives a signal in either of these cases:
• on each complete stroke of the pump
• on a pre-empty signal input.
Manual control
Dosing with manual on/off and manually adjustable dosing flow
In this operating mode, the operator enters all the settings on the pump.
Use the [Start/Stop] button to start or stop the pump.
Use the [Up/Down] buttons to increase or decrease the stroke frequency.
This can be done when the pump is stopped or when it is running.
Manual

Fig. 17 Display in manual control mode
The maximum stroke frequency displayed is automatically set according to the mains frequency and the gear ratio.
Memory function and excess contact signals
Contact signals that cannot be processed immediately, can be stored and subsequently made available to the pump for processing. A maximum of 65,000 contact signals can be stored.
• Without memory: If the pump is running when a contact signal is received, the signal is ignored. The pump executes the current dosing, then it is again ready to receive new contact signals, i.e. it rejects excess contacts.
• With memory: If the pump is running when a contact signal is received, the signal is stored in the memory. First, the pump executes the current dosing, then it processes the contact signals from the memory.
The following actions reset the memory:
• switching off the mains voltage
• switching operating mode.
The following actions do not reset the memory:
• remote on/off
• pressing the [Start/Stop] button
• continuous operation.

Construction
General description
The Grundfos DMX pumps are mechanical diaphragm dosing pumps. The strokes are generated by an eccentric which moves the diaphragm by means of a spring-loaded plunger. The discharge stroke is activated by the eccentric and the suction stroke by the spring return.
DMX model 221
The DMX pumps are designed for capacities between 1.3 and 2 x 166 GPH and a maximum pressure up to 232 psi.
The DMX pumps are fitted with a separation chamber. In the event of a diaphragm failure, the separation chamber prevents the pumped liquid from flooding the pump unit or other system components.
