## **Precautions** 

## I **Cam Positioner** 

## **Error Displays and Cancelling** 

When an error occurs, perform the following cancellation operation. (When the following errors occur, all outputs turn OFF except for the TACHOMETER output.) 

|ETER output.)|||
|---|---|---|
|**Display**|**Description**<br>|**Cancellation method**<br>|
||Set origin data error<br>|Reset the origin in the Programming Mode and return to the<br>previous mode.<br>|
||Memory error, when settings have been modified<br>**1.** The back-up battery has expired.<br>**2.** The contents of memory have changed due to noise or<br>another factor.|Switch to the Programming Mode and confirm all settings. Af-<br>ter correcting the settings, return to the previous mode.|

Return to the previous mode after corrections.<br>**1.** Encoder abnormality<br>**2.** Faulty Encoder connector contacts<br>**3.** Encoder rotation speed and response speed settings<br>**4.** Noise and surge protection|



After turning on the power, it takes approximately two seconds until normal operation, 

When the ON angle and OFF angle are the same value, no output will occur. 

## **Handling** 

Turn the operation power on or off instantaneously via a contact such as a switch or relay. 

Avoid operation in the following environments: 

**1.** An ambient temperature below -10°C or above 55°C. 

**2.** Very dusty locations. 

**3.** Very humid locations. 

**4.** Locations where corrosive gasses are generated. 

**5.** Locations with heavy vibrations or shock. 

**6.** Locations prone to water or oil. 

**7.** Locations with direct sunlight. 

For operation in environments with excessive electrical noise generation, separate the Encoder cords and the main unit of the H8PS from high-power cables that have noise or noise-generating sources. 

The external finish of the main unit is prone to organic solvents (thinner, benzene, etc.), strong alkali (ammonia, sodium hydroxide), and strong acid. Please avoid contact with theses chemicals. 

Store the devices between -25°C and 65°C. For storage below −10°C, power the unit up after letting it stand at room temperature for three hours. 

To perform dielectric testing, impulse-voltage testing, and insulationresistance measuring between the electrical circuitry and the uncharged metal parts when the unit is mounted in a control panel, first disconnect the wiring of the unit from the circuitry. (This prevents degradation of damage of internal circuitry in the event that part of the control-panel equipment has faulty voltage resistance or faulty insulation. The test voltage might go to the power-supply terminals of the main unit.) 

The Encoder consists of precision parts. Exercise care in handling, and make sure no excessive shock or pressure is applied to the Encoder. Especially make sure that the Encoder’s rotating shaft is not subjected to excessive force. 

The connections for the main unit connectors should have no undue stress applied. Wire cables accordingly. 

## **Angle Data Table** 

The H8PS uses an absolute Encoder with 256 divisions per revolution. To assist with programming, displays and settings may be done by conversion to 360 degrees by a switch on the front panel. The following table shows the conversions.

## ~~!WARNING~~ 

1. The H8PS has a built-in lithium battery. Be sure to dispose of the old H8PS properly, as lithium batteries are likely to explode if incinerated. 

2. Electrical shock hazard Never touch the input terminals of any H8PS Cam Positioner when power is being applied to the Cam Positioner. 

## I **Rotary Encoder** 

Make sure that the E6CP Encoder is not subjected to oil or water. If oil or water enters the interior, malfunctions may occur. For use in environments subject to water drops or oil, use the E6F. 

Make sure that there is no foreign matter in the Connector before connecting the Encoder. 

Rotary Encoders consist of precision parts. Their operation may be damaged if the Encoder is dropped. Be very careful with handling. 

When joining to a chain, timing belt, or gears, interpose a coupling and bearings before the Encoder.

Large mounting deviations (eccentric centers or angles) may cause an excessive load on the Encoder’s shaft, resulting in damage or drastically reduced life expectancy. Take care not to place excessive loads on the shaft. 

Keep the tightening torque around 0.49 N·m when fastening the rotary Encoder. 

If you insert a coupling on the shaft, do not hammer on the coupling or otherwise subject it to shock. 

## **Mounting Procedure** 

**1.** Place a coupling on the shaft. Do not screw the coupling and shaft tight. 

**2.** Fasten the Encoder. 

   - Do not insert the shaft to the coupling more than the length shown below. 

|below.||
|---|---|
|**Shaft coupling**|**Length of insertion**|
|E69-C06B|5.5 mm|
|E69-C10B|7.1 mm|

|E69-C10B|0.44 N·m|



**4.** Connect power supply and input/output lines. Make sure you turn off the power supply when wiring. 

**5.** Turn on the power and check outputs. 

Do not pull the wiring at a force greater than 29.4 N when the main unit is fastened and wired.

## I **Operation** 

The H8PS Cam Positioner receives angle signal inputs from the Encoder, and outputs the preset ON/OFF angles as control signals (cams number 1 to 8). 

## **Program Example** 

|**Program Example**|||||
|---|---|---|---|---|
|**Control output (cam number)**|**STEP 1**||**STEP 2**||
||**ON angle**|**OFF angle**|**ON angle**|**OFF angle**|

|2|0°|90°|180°|270°|

**Note:** 1. When the setting angles for STEP 1 and STEP 2 of same output are overlapped, the operation is as follows: 

2. The operating output  RUN OUT" does not turn ON during programming. The operation output turns ON with the timing shown in the diagram, but it remains OFF when an error occurs. Thus, you can use the output as a timing signal during operation, including test runs.
