[Notification of CAD Data Download Issue]
We regret to inform you that we are currently experiencing issues with downloading CAD data for some products.
We are investigating the cause of this problem. We apologize for any inconvenience this may cause and appreciate your understanding.
【Notification of Manufacturer Change for Panasonic Industrial Devices SUNX Products and Panasonic Industrial Devices SUNX Tatsuno Products】
From April 1, 2024, the terms "Panasonic Industrial Devices SUNX Co., Ltd." and "Panasonic Industrial Devices SUNX Tatsuno Co., Ltd."
in this page and in the manuals and other documents to be downloaded will all be replaced with "Panasonic Industry Co., Ltd." and applied accordingly.
Business > Industrial Devices > Automation Controls Top > FA Sensors & Components > Timers / Counters / FA Componets > Hour Meters > LH2H Preset Hour Meters(Discontinued Products) > Cautions For Use
We are sorry, the products have been discontinued. Please refer to the details of the discontinued products and the recommended substitutes list below.
|
Use highly reliable metal plated contacts.
Since the contact’s bounce time leads directly to error in the timer operating time, use contacts with as short a bounce time as possible.
|
Connect with an open collector.
Use transistors whose characteristics satisfy the criteria given below.
VCEO = Min. 20 V IC = Min. 20 mA ICBO = Max. 6 μA |
Also, use transistors with a residual voltage of less than 2 V when the transistor is on.
* The short-circuit impedance should be less than 1 kΩ.
(When the impedance is 0 Ω, the current coming from the start input terminal is approximately 5 mA and from the reset input terminal is approximately 1.5 mA.)
Also, the open-circuit impedance should be more than 100 kΩ.
|
When wiring, use shielded wires or metallic wire tubes, and keep the wire lengths as short as possible.
Since the transistor output of hour meter is insulated from the internal circuitry by a photo-coupler, it can be used as an NPN output or PNP (equal value) output.

If a malfunction occurs, one of the following displays will appear.
Display | Contents | Output condition |
Restoration procedure |
Preset values after restoration |
---|---|---|---|---|
Err-00 | Malfunctioning CPU |
OFF | Enter front reset key or restart hour meter | Preset value at start-up before the CPU malfunction occurred |
Err-01 | Malfunctioning memory* |
"0" |
* | Includes the possibility that the EEP-ROM’s life has expired. |
---|
The EEP-ROM is overwriting with the following timing.
Operation mode | Overwrite timing |
---|---|
G (Totalizing ON delay) mode |
Change of preset value or when power is OFF after start and reset input turns ON |
Other modes | When power is OFF after changing preset value |
|
Before using a panel mounting type, please pull and remove the insulation sheet in the direction of the arrow.
In consideration that the product might be stored for long periods without being used, an insulation sheet is inserted before shipping.
Remove the insulation sheet and press the front reset button.
|
|
The operation part of the panel installation type (installation frame type) is constructed to prevent water from entering the unit and a rubber gasket is provided to prevent water from entering the gap between the unit and the panel cutout.
There must be sufficient pressure applied to the rubber gasket to prevent water from entering.
Be sure to use the mounting screws when installing the mounting frame (ATH3803).
Note: | The one-touch installation type is not waterproof |
---|
|
|
* | When installing the mounting frame and rubber gasket please remove the pre-attached o-ring. |

(When dew forms the display may vanish and other display errors may occur.)
