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

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.

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.

10. 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.

13. How to Mount

Step-1.Insert the controller through the panel cutout.

Step-2.Insert the mounting bracket into the mounting groove at the top and bottom of the controller and push the mounting bracket forward until the bracket stops at panel wall.

Step-3.Insert and tighten screws on bracket to secure the controller in place.
