User Operation

The counter requires positive input pulses from PNP proximity switches or similar.This text should be replaced with information about you and your business

If using an NPN (negative pulse) sensor, a 1k ohm 0.5W  pull-up resistor is required between V+ and signal (Sig) on the LC1.

If using a 2 wire proximity switch , a 1k ohm 0.5W  pull-up resistor is required between V+ and signal (Sig) on the LC1.

The LiquiCount LC1 is a dual-channel, liquid counter designed for precise measurement and logging of two separate liquid or item streams. It features a user-friendly LCD interface, button-based navigation, EEPROM-backed configuration, and pulse outputs for external devices.

1. When power is supplied to the LC1 counter. The display will show ‘Booting…’,
2. After 2.5 seconds, the splash screen Will appear showing the software version.
3. The home screen will then appear, showing the channel labels and the total number of units delivered since the last reset. As pulses are received and converted to units, the units count will increase.

1. To reset the counts to zero, press the RESET button And the reset confirmation screen will appear.

2. Pressing the UP button cancels the reset and returns you to the home screen, displaying the current values.

3. To confirm the reset, press the ENTER button, which will return you to the home screen with zero counts.

The Settings Menu offers access to five core configuration functions of the LiquiCount LC1 system: Calibration, Sensor Voltages, Test Pulses, Label Editing and Units. These functions are accessed via a protected menu, navigated using the physical buttons.

1. To access the settings menu, press the enter button for five seconds or until the ‘ENTER CODE TO ACCESS SETTING’ message is displayed. Press the ‘UP’ button three times and then the ‘DOWN’ button once.
2. Note: If the count is greater than zero, you will receive this message. Use the reset button to reset the values back to zero. (See ‘Resetting Counts’). Once the counts have been reset you can try again.
3. If the combination is wrong a ‘WRONG CODE ENTERED’ message will be displayed.
4. When the correct sequence has been entered, the menu will appear.

The main menu consists of five options. To navigate and cycle through the menu, use the UP and DOWN buttons. Select an option using the ENTER button. The screen only shows two rows at a time.

Calibration ensures the system correctly converts input pulses to litres, gallons or items.

1. To calibrate, select “Calibrate” from the main menu.
2. The display will show both Channel 1 K-Factor and Channel 2 K-Factor values which are the number of pulses per unit.
3. To edit the K Factor for a specific channel, select the channel and press ENTER. The display will indicate that It’s now in edit mode, by moving the arrow to the right of the label.
4. The UP and DOWN buttons increase or decrease the K factor value. A single press of the up or down button changes the value by 0.1. Pressing and holding either up and down button will change the value faster.
5. When the required value is displayed, press the enter button to save it.
6. Once you’ve entered and saved your values, use the UP and DOWN buttons to scroll to the bottom of the menu. Pressing ENTER on the ‘BACK’ option will return you to the main menu.

Note: If the LC1 is being used to count items, then no calibration is required other than to reset both K-factors to 1.

The K-factor for each channel changes how many pulses are counted per unit (G/L). By default, the K-factor for each channel is set to 1.  Change the K-factor as required until the displayed count equals the delivered quantity. Deliver fluid into a calibrated container.  If the display:

• Reads less than that delivered, decrease the K-factor.
• Reads more than that delivered, increases the K factor.

Continue to measure and compare until the display equals the delivered quantity.

Note: Any change to the fluid system may affect its accuracy. Re-check the calibration regularly.

Prior to use, you must ensure that the sensor voltage is correctly set for both channels. If the sensors in the system require 24 V, you will need to set them accordingly. If they require 5 V then you can start using it straight away as the default value for both channels  is 5 V.

1. Select sensor voltage from the main menu.
2. The display will show both channels and the current voltage setting. Press the enter button to edit a channel.
3. Select the voltage sensor using the up-and-down buttons. The current sensor voltage selected is Indicated with ‘ON’ present for the chosen sensor voltage.
4. Confirm the sensor of voltage selected. To cancel the voltage sensor selected press the up button.

This function outputs 10 test pulses on each output channel to ensure that a printer, if connected, reads correctly.

1. Select generate pulses from the main menu.
2. The pulses will begin automatically, Ten pulses on channel one and then ten pulses on channel 2.
3. When both channels have completed the test pulses, you will be given the chance to run the test again.
4. Pressing the UP button will display the main menu. Pressing the ENTER button repeats the test pulses.

1. Select Edit Labels from the main menu. Use the UP and DOWN buttons to move through the available options, then press ENTER to select. The Edit Labels menu provides the following options:
   EDIT CH1 LABEL
   EDIT CH2 LABEL
   DISABLE CH2 LBL / ENABLE CH2 LBL
   BACK
2. To edit a channel label, select the required channel and press ENTER.
3. To enter characters, use the UP and DOWN buttons to scroll through the available character AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz1234567890- {blank space}
