Frequently Asked Questions
How do I set the operation mode on the LC4H-R6-DC24VS?
The operation mode can be set using the DIP switches located on the side of the unit. Refer to the datasheet for specific DIP switch configurations to select the desired input and output modes.
What types of inputs can the LC4H-R6-DC24VS accept?
The counter accepts contact point inputs and non-contact point inputs such as open collector transistors. Ensure that the characteristics of the transistors used satisfy the specified criteria in the datasheet.
Can the LC4H-R6-DC24VS be used in outdoor environments?
The counter is designed to conform to IP66 weather-resistant standards, which means it can withstand water and dirt ingress. However, it should be installed in a location that minimises exposure to harsh environmental conditions.
What is the maximum counting speed of the LC4H-R6-DC24VS?
The maximum counting speed of the counter is switchable between 30 Hz (cps) and 5 kHz (Kcps), selectable by a DIP switch.
How can I change the set value on the LC4H-R6-DC24VS?
The set value can be changed using the seesaw buttons located on the front of the unit. You can increase or decrease the value of the corresponding digit of the set value display even during counting.
What should I do if the LC4H-R6-DC24VS is not responding correctly to input signals?
First, ensure that the input signals meet the specifications detailed in the datasheet. Check the wiring and DIP switch settings for accuracy. If the issue persists, consult the self-diagnosis function of the counter for further troubleshooting.
Is there a memory backup in case of power failure for the LC4H-R6-DC24VS?
Yes, the counter features power failure memory retention. The set value and displayed counts are retained in memory, so no data is lost during a power failure.
What are the mounting options for the LC4H-R6-DC24VS?
The counter can be surface-mounted using the pin type timer or flush-mounted using the built-in screw terminal type. Mounting frames and rubber gaskets are provided with the timer for secure installation.
How can I protect the LC4H-R6-DC24VS from power supply surges?
To protect the counter from power supply surges, use a surge absorbing element as specified in the datasheet. This will prevent potential damage to the internal circuits.
What should I consider when connecting an inductive load to the LC4H-R6-DC24VS?
When connecting an inductive load, use a diode to absorb the reverse voltage from the load. Ensure the diode's rating is suitable for the load's characteristics.
