How to identify newer and older controllers

The controller for HL-T1 series, HL-AC1(P), has been upgraded from the shipment in July 1st, 2019.

It can not be used new and previous controllers mixed when using with calculation unit, HL-AC1-CL.
Some functions are different depending on the versions. Please refer to each new and previous manuals for functions in detail.
>>Go to "Manual download" page.

■How to distinguish the controllers
The serial No. on main unit and OS label will be changed as below.

Before the upgrade (Software Ver.2/Ver.1)	After the upgrade (Software Ver.3)
Serial No.：0****(It starts with 0.**)	Serial No.：9****(It starts with 9.**)

Functions

Function

Details

Zero reset function

The following tasks can be done by executing zero reset.

・	The display value can be set at “0”.
・	The linear output when the display reads “0” is made the center output value of the 2 points set by monitor focus. (In the default state, the current output is 12 mA and the voltage output is 0 V.)

Auto scaling function

The auto scaling function selects whether to display the laser beam reception amount in the main-digital display in “mm” units or in “%” units, and determines whether the amount of laser beam received or the amount of laser beam interrupted is displayed. With the set standard laser beam reception amount as the reference value, the current laser beam reception amount (laser beam interrupted amount) is scaled automatically and is displayed as well as being output.

Standard received light setting

This function registers and stores the current laser beam reception amount in memory as the standard laser beam reception amount. The laser beam reception amount during full laser beam entry becomes the 100 % laser beam reception amount’s full scale (F.S.). If this function is used, the display and the linear output are set on the full scale (F.S.) automatically. It can also be used to correct the laser beam reception amount when there is a change in the laser beam reception amount due to dirt, etc. on the front glass.

Scaling function

The scaling function is a function that changes the display value to the desired amount with respect to the setting value. At the desired distance, the display value can be input and changed.

Hysteresis width setting function

This function sets the hysteresis to the desired value.

Monitor focus function

With this function, the linear output range and inclination, etc. with respect to the display value can be specified. Setting is done by determining the 2 output values with respect to the desired display values.

Differential function

This function makes the amount of change in the measured value an output value. Use this function when measuring if you are paying attention to changes in measured values, as when counting the number of workpieces, etc.

Display reverse function

The digital display’s direction can be selected. The forward direction or the reverse direction to match the direction of installation on the equipment can be selected.

ECO display function

This function makes the display dark and saves electric power.

Display digits limitation function

This determines the number of display digits in the main-digital and sub-digital displays. If the number of digits is limited, the digits are turned off beginning with the lowest order digit.

Zero reset memory function

This selects whether or not to save the zero reset level in memory when the power is turned OFF. If you desire to reproduce the zero reset level from the previous operating session when you turn the power ON again, then enable this function. If this function is enabled, the zero reset level data are written into the EEPROM each time.

Key lock function

The controller’s key input can be disabled. Once the key input is disabled, the controller will not accept any key inputs until the key lock is released. Use this function to avoid changing the setting by mistake.

Connection

This product is made to satisfy the specifications when the sensor head is combined with the controller. In any other combination, not only may it not satisfy the specifications, but could be the cause of breakdown. So by all means, use it so that there is a combination of the sensor head and the controller.

When in the RUN mode, it displays the threshold value, voltage / current value, light reception amount or resolution. When in the THR mode, it displays the respective threshold values. In reverse mode, the top and bottom are displayed in reverse.

[5]

Enable indicator

[6]

Zero reset indicator
(ZERO)
(Green LED)

Lights up when the zero reset function is enabled.

[7]

• RUN mode:	Measuring mode
• THR mode:	The threshold values are set in this mode.
• FUN mode:	Each of the settings are set in this mode.

[8]

Threshold value select switch

When in the THR / RUN mode, this switches the set threshold value (HIGH / LOW).

• FUN mode:	When the set value is blinking, the value is set. When the setting is being initialized, pressing for a long time executes initialization.

Others

This product outputs the judgment of the laser light analog quantity. Since there is variation in the light intensity between the center and the edges of the detection area, and the emitter side and the receiver side, the “display value” does not equal “the actual dimensions”, so caution is necessary.
Use the displayed dimensional value as a criterion.
If the object being measured has a mirror surface or is a transparent body, it may be impossible to measure it accurately, so please exercise caution.
Absolutely do not attempt to disassemble this product.
