Safety Precautions Power ON Reset After the power is turned ON, it will take approx. 3.5 seconds for the measurement to start. The judgment results will be output after the sampling rate has elapsed. General Precautions Other Precautions • At startup and during operation, be sure to monitor the functions and performance of this product and confirm normal operation. • We recommend that you take substantial safety measures to avoid any damage in the event that a problem occurs.

1. Before Use Part Names and Functions Sensor Amplifier Unit This chapter gives an overview of the SK Series as well as the name and function of each part. SK-1000 Checking the Package Contents Expansion unit connector*1 The following equipment and accessories are included in the package. Before using the unit, make sure that all items are included.

2. Sensor Head Unit SK-050 Installation and Connection This chapter describes precautions when installing and connecting the SK Series. Mounting and Wiring the Sensor Amplifier (3) Temperature/humidity sensor Mounting the Sensor Amplifier (1) Sensor indicator light SK-1000 1 (2) Surface potential sensor Align the tab at the bottom of the amplifier body with the DIN rail. While pushing the amplifier in the direction of the arrow (1), push down in the direction of the arrow (2).

4 Install the end units (OP-26751: 2 units in a set, optional accessory) on both sides of the amplifiers (main and expansion units). Secure the end units in place with screws on top (2 on each end unit). Connecting and Mounting the Sensor Head Mounting the Sensor Head The end units are mounted in the same way as the amplifiers. Attach the sensor head using the dedicated mounting bracket. When you attach the sensor head, be careful not to touch the aperture. Doing so may lead to malfunctions.
PAGE 6
NOTICE Reference Attaching the sensor head cable connector (OP-84338: optional accessory) Be sure to fasten screws from the ion balance plate side. If fastened from the main body side, the ion balance plate can contact other parts, resulting in incorrect measurement. Cut the sensor head connection cable to the required length and attach the new connector to use the sensor. The ion balance plate can be mounted from either side of the sensor head.

3. Basic Operations Operations on the Main Screens R.V. (Internal Measurement Value) and P.V. (Judgment Value) This chapter describes basic operations and settings for the SK Series. This section describes R.V. (Internal Measurement Value) displayed on the sub display (lower level) and P.V. (Judgment Value) displayed on the main display (upper level).
PAGE 8
(5) LO side setting value screen The lower limit of the acceptable range (tolerance setting value) for the target is displayed. This setting value can be changed. If the judgment value (P.V.) falls below the value set here, the LO judgment output turns on. "Changing the Tolerance Values" (page 9) (6) R.V. display screen The internal measurement value (R.V.) is displayed. The displayed value is not held even if a hold function is enabled.
PAGE 9
Changing the Tolerance Values Zero Shift Function (Shifting the Internal Measurement Value (R.V.)) The tolerance values consist of the upper limit value (HI side setting value) and the lower limit value (LO side setting value). By setting these values, judgments are made in three levels: when the judgment value (P.V.) goes beyond the upper limit (HI judgment), when the judgment goes beyond the lower limit (LO judgment) and when the judgment is within the acceptable range (GO judgment).

4. How to Switch Banks Banks can be switched by either of the methods below. • Front panel commands on the amplifier. • Use the external inputs (Bank A input, Bank B input)* This chapter describes the various functions of the SK Series. Basic Settings and Advanced Settings * If the bank switching method is set to external input, and bank A input or bank B input is set for the external input, banks can be switched with the external input.

Error Displays and Corrective Actions Non-Error Displays and Corrective Actions When an error occurs, an error message appears on the sensor amplifier. Reference When the judgment value (P.V.) is "-----" the judgment outputs turn OFF (When Normally Open is set), the analog voltage output is 5.5 V and the analog output current is 3.0 mA. • If an error occurs, the judgment output changes to the error status and the alarm output turns OFF.
PAGE 21
Display Screen and Output Factory Setting (Default Value) List Normally, the judgment value (P.V.) is displayed on the main display (upper level). This section describes the judgment output and analog output status when displays other than numbers appear on the main display. Reference The judgment indicator on the sensor amplifier operates in the same way as Normally Open regardless of the output state setting.
