2 SETUP This chapter describes the method used to install and connect the EV Counter and make its initial conditions. 2.1 Installing the EV Counter Both the front and rear panels of the EV Counter have four mounting holes. Use the fixing legs and junction brackets which come as the standard accessories to install the EV Counter. a) The fixing legs (1) Attach the fixing legs (4 places) on the counter main unit using the supplied screws.
PAGE 18
2.2 Connecting Cables IMPORTANT • Connection should be made only after the power to the main unit and to the partner device of the connection have been turned off. Otherwise, the counter main unit and the connected device will be damaged. • Use a 12 - 24VDC power supply with a control output current of 1A or greater. Do not draw power from a source which is used by highpower equipment. • Do not route the power cable, I/O cable, RS232C cable, RS LINK cable, or gage connection cable with other power cables.
PAGE 19
2 SETUP 2.2.2 Connecting the D-EV (External Display Unit) If a D-EV (External Display Unit) is used, make the necessary connections according to the following procedure. (1) Connect the RS LINK OUT connector of the EV Counter to the RS LINK IN connector of the D-EV using an RS LINK connection cable. EV Counter RS LINK IN OUT RS LINK IN OUT D-EV RS-232C NOTE RS LINK connecting cable (optional) Always use the RS LINK connection cable specified by Mitutoyo. Refer to section 8.3 Optional Accessories.

2.3 Power On When the power source is connected to the EV Counter, it enters the counting stand-by state. To start operation and enter the counting state, quit the stand-by state. TIP The counting stand-by function is an alarm function that is entered if there is a power interruption during use. a) If a D-EV is not connected (1) If the EV-16P or EV-16D is used,enter the RS-232C command or I/O signal (a HOLD signal to clear the error) in the EV Counter.
PAGE 21
2 SETUP (3) If the EV-16Z is used, push in the spindle of the connected gages to pass through the origin one after another, and each time it passes through the origin the corresponding bar display of the CH starts flashing. [Display on the D-EV] UNIT +NG GO -NG (4) If the EV-16Z is used, push in the spindles of all connected gages to pass through the origins, then the counter enters the counting mode.

3 SETTING PARAMETERS This chapter describes the method used to set the parameters required to use the EV Counter. 3.1 Setting Parameters (with D-EV) Before using the EV Counter, various parameters must be set up. This section explains the setup method using the essential parameters, "gage resolution" (for EV-16P and EV-16Z) and "designation of available axes", as examples. NOTE For the resolution of 0.1µm setting, a D-EV is absolutely necessary. 3.1.
PAGE 24
3.1.2 Specifying the gage resolution (for EV-16P and EV-16Z) In order to connect a gage with a resolution that is not 1µm, the counter must modify its resolution setting to that of the connected gage. (1) Press the Fn key repeatedly to display Parameter No. 12 and the INPUT number of A. [Display on the D-EV] UNIT +NG GO -NG (2) Press the P.SET key to modify the setup value. (Refer to section 3.1.5 List of parameters.

NOTE If an error occurs during a parameter, preset value, or tolerance value setting operation, the error code will be displayed only after the counting state has been restored. However, the error code will be output immediately. In the high-speed mode, an error code will be output only if the CH that caused the error is specified for output. If the EV-16Z is used, perform origin re-input after removing the error cause to cancel the error.
