Timer / Counter / Tachometer Instruction Sheet
Thank you very much for purchasing DELTA CTA series. Please read this instruction sheet before using your CTA series
to ensure proper 3operation and please keep this instruction sheet handy for quick reference.
DANGER! Caution! Electric Shock! When the power is on, DO NOT touch the AC terminals in case an
electric shock may occur. Make sure the power is disconnected when you check the unit inside.
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 2mm2, 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.

Key Operation
Increase and decrease SV or change parameter settings.
Left move 1 digit of the selected digit. The indicator of the selected digit will flash.
MODE
Save the set parameters or switch among functions.
LOCK
Prevent settings from being changed. Key-protected mode still works after the power is switched off. Press

 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
Output 2 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 Output 2 (pulse)
executes 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.

Delay time after switching on the power :The tachometer will start to run when the set delay time is due
after the power is switched on. (Range of delay time: 0.1 ~ 99.9 secs.)
Setup average value of input filter :Range for obtaining average (n = 0 ~ 3). This parameter obtains the
average of 2n input data for more stable output value.

 Timer + Counter 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
y RCY2, SCON, STON, STOFF in output mode of Timer function
y 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.
 Easy DIP Switch Setup
Users can use DIP switch to setup parameters. When DIP is switched to ON, the corresponding parameters can only be
read, not changed.
