Cautions during Use

• Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
• Power supply should be insulated and limited voltage / current or Class 2, SELV power supply device.
• Use the product, 0.1 sec after supplying power.

Description of Function

Switching display in setting display part

1. stage preset value and 2-stage preset value are displayed each time when pressing [MD] key in 2-stage preset model.

• In timer, it is available for output operation mode: OND, OND.1, OND.2 only

BATCH counter

• Counting value display part: BATCH counter value, setting display part: BATCH counter setting value is displayed.
• In counter operation, count the number of reaching value of CT6M-1P□□ to preset value, and CT6M-2P□□ to 2-stage preset value.
• In timer operation, count the number of reaching setting time.
• Output operation mode: in case of FLK, count the number of reaching T.off setting time and T.on setting time

BATCH counter operation

BATCH counting value is increasing until BATCH reset signal applied. BATCH counting value will be circulated when it is over 999999

BATCH RESET

• If pressing [RST] key on the front side or the signal to BATCH RESET terminal on the back side panel, BATCH counting value will be reset and BATCH output maintains OFF state.
• When selecting voltage input (PNP), short terminals 10 and 14, or when selecting no-voltage input (NPN), short terminals 11 and 14 to reset.

Applications

• [counter]
• In case, put 5 products in a box then pack the boxes when they reaches to 200.
• PRESET = 5, BATCH = 200
•  When the count value of counter reaches to the preset value 5, the control output (OUT) will be on, and at this time the count value of the BATCH counter will be increased by 1.
• The control box which is received the control output (OUT) repeatedly controls conveyor to move the full box and to place the next empty box for standby.
• When the BATCH counting value reaches to 200, BATCH output will be ON. Then the control box stops conveyor and provides a control signal for packing.

[timer]

• Fills milk into the bottle for 3 sec when 500 bottles are filled
• Setting time = 3 sec, BATCH = 500

Start Point (counter)

• This function is that start at initial value set at Start Point value.
• When reset is applied, the present value is initialized to Start Point value.
• After Count Up at output operation mode: C, R, P, Q, present value starts at Start Point value.

Prescale (counter)

This function is to set and display calculated unit for actual length, liquid, position, etc. It is called ‘prescale value’ for measured length, liquid, or position, etc per 1 pulse.

• When moving L, the desired length to be measured, and P, the number of pulses per 1 revolution of a rotary encoder, occurs, prescale value is L/P.
• Application
• Diameter of pulley connected with encoder is 22 mm, the number of pulses by 1 rotation of encoder is 1,000
• Select decimal point: —–.-, prescale decimal point: —.— and set prescale value: 0.069, it is available to control conveyor position by 0.1 mm unit.

Counter Operation

Input operation mode

1. A should be over min. signal width, B is over 1/2 of min. signal width. If the signal is smaller than these widths, it may cause counting error (±1).

• Min. signal width by counting speed

Output operation mode

• Out output of 1-stage preset model operates as same with the OUT2 output of 2-stage preset model.
• OUT1 output of 2-stage preset model is operated One-shot output or retained (Hold) output. (except S, T, D of input operation mode)
• OUT1 output could be set to 0 in all modes and 0 value output turns ON.
