Instruction Sheet

5011646001-CTE1

Thank you very much for purchasing DELTA CTA series. Please read this instruction sheet before using your CTA series to ensure proper operation and please keep this instruction sheet handy for quick reference.

¾ DANGER! Caution! Electric Shock! ¾ When the power is on, DO NOT touch the AC terminals in case an electric shock may occur. ¾ Make sure the power is disconnected when you check the unit inside.

¾ CTA series is an OPEN-TYPE device. They are intended for installation completely within an overall panel and are for use

in counting or timing application. If it will cause serious injury to workers or damage on other equipments when used in a dangerous environment, please make sure it is installed in an automatic safety protection device.

Precaution

1. Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, width 7.0mm), hole (diameter

3.2mm). Screw size: M3x6.5 (with 6.8x6.8 square washer). Recommended tightening torque: 0.4 N.m (4kgf.cm). Applicable wire: solid/twisted wire of 2mm

, 12AWG to 24 AWG. Please be sure to tighten them properly.

2. Prevent dust or metallic debris from falling into the device and cause malfunctions.

3. DO NOT modify or uninstall the device.

4. DO NOT use empty terminals.

5. Make sure the wires are correctly connected to proper terminals.

6. Keep away from high-voltage and high-frequency environment during installation in case of interference.

7. Prevent using the device in premises which contain: ․Dust or corrosive gas ․High humidity ․High radiation ․Vibration and shock

8. CTA series is an open-type device. Make sure to install it in an enclosure to prevent dust, humidity in case of an electric

shock.

9. Please make sure the power cables and signal device are installed correctly before switching on the power; otherwise

serious damage may occur.。

10. DO NOT touch the terminals or repair the device when the power is on; otherwise an electric shock may occur.

11. Please wait for one minute after the power is switched off to allow the capacitor to discharge and DO NOT touch the

internal wiring within this period.

12. Use dry cloth to clean the device. DO NOT use acid or alkaline liquid to clean the device.

Counter Function

Counter functions include 1-stage counting, 2-stage counting, batch counting, total counting and dual counting.

1-stage Only 1 SV is allowed. See “output modes of counter”. 2-stage 2 SVs, 2 PVs are allowed. See “output modes of counter”.

Batch Apart from the counting of PV and SV, when PV=SV, the batch counting adds 1 and clear PV as 0 for

recounting till the batch counting equals batch SV.

Total Total counting adds up all the counting values till they reach SV for output. Dual CP1 and CP2 can be independent counters, but the counting speed can only reach 5kHz. CP1 and CP2

can execute addition

or subtraction .

Output modes of counter :

The output of SV can be 1-stage or 2-stage. When the output is set as 1-stage, Output 2 will be the same as the Output 1. The output modes include: F, N, C, R, K, P, Q, A, S, T, D

F When PV reaches SV, output is enabled but counting continues. Recounting starts after reset signal is over.

Output 2 remains.

N When PV reaches SV, output is enabled but counting stops. Recounting starts after reset signal is over. Output 2

remains.

C When PV reaches SV, recounting executes automatically. Output 2 is pulse output. Output 1 remains till O

is over.

R When PV reaches SV, counting stops till Output 2 (pulse) is over for recounting. Output 1 remains till Output 2 is

over.

K When PV reaches SV, output is enabled but counting continues. Recounting starts after reset signal is over.

P When PV reaches SV, output is enabled and recounting is automatically executed. But display of counting

remains till Output 2 (pulse) is over.

Q When PV reaches SV, output is enabled but the counting continues. Recounting starts after Output 2 (pulse) is

over.

A When PV reaches SV, output is enabled but the counting stops. Recounting starts and O

after reset signal is over.

S When PV ≥ SV1, Output 1 is enabled. When PV ≥ SV2, Output 2 is enabled

T When PV ≤ SV1, Output 1 is enabled. When PV ≥ SV2, Output 2 is enabled.

D When SV=PV, output is enabled but counting continues. Addition and subtraction modes are valid.

The time of Output 1 and Output 2 (pulse) can be setup separately, ranging from 0.01 to 99.99 secs. Recounting refers to counting up or addition/subtraction counting starting from 0 and counting down starting from SV. The counting range: -99999~999999. The counting will restart from 0 if the counting exceeds the range.

Save the data before power off : When is set, the current PV will be saved. When is displayed, the

Timer + Counter Mixed Function

In Timer + Counter function, SV1, PV1 and Output 1 are for Timer; SV2, PV2 and Output2 are for Counter. DIP switch is disabled. All timer and counter functions remain except

․ RCY2, SCON, STON, STOFF in output mode of Timer function ․ Command up/down, Individual up/down, quadrature counting in input mode, S, T, D in output mode of Counter function

Only 1-stage counting in Counter function is available.
