2. GENERAL

The Model SKYD Alarm Unit provides two types of alarms : absolute alarm that is output after comparison of one input signal with one or two alarm set points, and deviation alarm that is output after comparison of the deviation between two inputs with two alarm set points. Direct or reverse alarm action can be selected for each of the alarm output set points. The front panel is provided with an alarm LED indicator lamp for confirming alarm relay action (when relay is energized). The JHT200 Handy Terminal On the SKYD model with display setter (SKYD-x04), input indication (engineering unit) can be displayed and alarm set points can be displayed / set on the front panel.

*1: The modular jack conversion adapter (E9786WH) is required for connecting the JHT200 Handy Terminal to the

Alarm Unit.

The 5 pin-connector type communication cable (F9182EE) and modular jack conversion adapter (E9786WH) is

required for connecting the BT200 BRAIN Terminal of YOKOGAWA ELECTRIC Corporation

3. INSTALLATION

For details of the installation procedure and wiring precautions, refer to the technical information “YEWSERIES 80 Installation Manual” (TI 1B4A9-01E) or the instruction manual “Installation of Rack-Mounted Instruments” (IM 1B4F2-01E).

3.1 External Wiring

(a) All cable ends must be furnished with crimp-on type solderless lugs (for 4mm

screws).. (b) Draw out the internal unit from the rack case. (c) Connect the cables to the correct terminals referring to Figure 3-1. (d) Return the internal unit into the rack case after completing the wiring. (e) Always return the terminal block cover to its original position after completing the

wiring.

NOTE

3-1

The terminal block cover cannot be returned to its original position if the internal unit is not installed its original position in the rack case. Securely return the terminal block cover because it also functions as lock for the internal unit.

3.2 Example of Alarm Wiring

The SKYD alarm unit provides various types or alarms depending on the setting of the alarm action or the method of connecting the alarm output terminals. Thus, the necessary wiring should be made with reference to the following two examples:

3.2.1 High-limit and High-high-limit Alarms

Set the direct action (DIRECT) for the alarm actions of both alarms 1 and 2. Then wire the terminals as illustrated in Figure 3-2.

4. PRINCIPLES OF OPERATION

4.1 Principle of Operation

Input signals are converted to digital data by the A/D conversion circuit. The resulting digital data is processed (square root calculation, etc.) by the microcomputer, and the alarm relay is then energized/de-energized by alarm calculation processing (comparison, etc.).
