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.).

z Explanation of Input processing block
A/D conversion: Performs A/D conversion on input signals.
Normalization: A/D-converted signals are converted to a scale of 1 to 5 V DC. (INPUT1)
Square root calculation (LINEARIZE1): When square root calculation is set to ON, the input processing block performs
square root calculation on the input signal.
The low-cut point (LOW CUT1) can be set to the square root calculation. The figure
below shows operation when the input signal is near the low-cut point. This low-cut point is provided with a hysteresis of 0.2%.

Scaling (SKYD-x04 only):
The display in engineering unit is available according to the SCH1, SCL1 and DP1
parameter settings.
The value after scaling (or, when the bias function is used, the value obtained by
adding bias to this value) becomes PV1.
SCH1, SCL1, DP1 setting (default: 0.0 to 100.0)
<Setting Method> (1) Set the decimal point position matched to the unit system actually in use at DP1. (Example: two digits past the decimal point) (2) Register the measuring input scale range at SCH1 and SCL1. (Example: SCH1=20.00, SCL1=0.00)

IM 01B04K01-02E 10th Edition : 2004.05.01-00
<Toc> <4. PRINCIPLES OF OPERATION>
NOTE
Reverse scaling (SCH1 < SCL1) is also possible. A setting error occurs when SCH1 is set to equal SCL1.
Bias:
A bias value (BIAS1) can be added to scaling values. This allows error to be compensated when there is an error between the input value
and the indicated value. Bias can be set within the range ±10% [(SCH1 - SCL1) x 0.1] of the scaling width. The input value displayed on the display setter on the front panel (PV1 in the
BRAIN communications parameter) is the value after addition of bias.
z Explanation of Alarm detection block In the following description, n is "1" for SKYD-10x, and "1" or "2" for SKYD-20x.
Alarm detection n:
Performs alarm detection.
ALMn ACTION: Alarm action
Direct .................. The alarm state is entered when the input value exceeds the
preset alarm set point.
Reverse...............The alarm state is entered when the input value is at the preset
alarm value or lower.
SET POINTn: Alarm set point
HYSTERESISn: Alarm hysteresis
ON DELAYn: Alarm ON delay
Sets the dead time until the alarm turns ON. An alarm state is entered when the input value is in the alarm range for the duration
set at ON DELAYn. If input returns to the normal range before the time set at ON DELAYn is reached,
the alarm does not turn ON.
OFF DELAYn: Alarm OFF delay
Sets the dead time until the alarm turns OFF. A normal state is entered when the input value is in the normal range for the
duration set at OFF DELAYn. If input returns to the alarm range before the time set at OFF DELAYn is reached,
the alarm does not turn OFF.
4-4
NOTE
When the ON delay/OFF delay settings are changed during a delay, delay action is
discontinued, the current alarm or normal state is returned to, and the delay action is performed from that state.
The alarm function does not work for 3 seconds after power ON.

6. MAINTENANCE

This chapter describes the simple maintenance procedures and fuse replacements that can be done in the instrument room or service shop.

6.1 Test Equipments

For efficient maintenance of this alarm unit, it is recommended that the user have the following test equipment manufactured by Yokogawa or their equivalent.
6-1
Device Model Name Number
DC voltage/current standard 7651 1 each 2 units are required in the
Analog tester 2415 1 Handy Terminal JHT200 (BT200) 1 Modular jack conversion adapter Part No. E9786WH 1

6.2 Check of Input

The JHT200 Handy Terminal is required for checking input.
NOTE
For details of operation and adjusting procedures of JHT200 Handy Terminal, refer to the instruction manual ‘‘JHT200 Handy Terminal’’ (IM JF81-02E).
Do not turn off the power of the instrument during adjustment.
Remarks
of Units
case of the deviation alarm

6.2.1 Check for SKYD-10x and SKYD-20x

Only one input is supported on the SKYD-10x/20x. The adjustment parameters are as follows: P3: Zero Adjustment (Input 1) P4: Span Adjustment (Input 1) For details on adjusting these parameters, refer to the instruction manual "JHT200
Handy Terminal (IM JF81-02E)."

6.2.2 Check for SKYD-30x

Two inputs are supported on the SKYD-30x. Perform "6.2.1 Check for SKYD-10x/20x" for both Input 1 and Input 2.
The adjustment parameters are as follows: P3: Zero Adjustment (Input 1) (Rev No.3 or later models) P4: Span Adjustment (Input 1) (Rev No.3 or later models) P7: Zero Adjustment (Input 1) (Rev No.1 or No.2 models) P8: Span Adjustment (Input 1) (Rev No.1 or No.2 models) P5: Zero Adjustment (Input 2) (Rev No.3 or later models) P6: Span Adjustment (Input 2) (Rev No.3 or later models)
IM 01B04K01-02E 10th Edition : 2004.05.01-00
<Toc> <6. MAINTENANCE>

6.3 Replacement of Fuse

When the fuse blows or requires replacement, replace it according to the following procedure. Recommended replacement interval: About 3 years.
Before replacing a fuse, turn off the power to the instrument.
NOTE
When a fuse has blown, check for the cause first because a fuse itself may not be responsible for the problem. Then replace the fuse.
Use the dedicated fuse (S9510VK). Do not use a fuse for other products.
(1) Remove the fuse holder cap, then pull the fuse out in the direction shown in Figure
6-1.
(2) When installing a new fuse, use a fuse with the correct rating. Fasten the cap
securely.
6-2
Figure 6-1 Replacement of Fuse

6.4 Replacement of Capacitor

Degradation of the aluminum electrolytic capacitor used in the power supply unit depends on operating temperature condition or operating environment. Recommended replacement interval: 5 to 10 years.
NOTE
Ask your nearest Yokogawa sales staff to replace the capacitor.
Do not replace the capacitor by yourself, because the parts number of power
supply unit (refer to CMPL 01B04K01-02E) and capacitor to be used are different according to the power supply specifications.
IM 01B04K01-02E 10th Edition : 2004.05.01-00
<Toc> <6. MAINTENANCE>

6.5 Replacement of Relays

The relays used for alarm action are influenced and deteriorate according to the connected load and number of ON/OFF switching operations. We recommend replacing relays at the following replacement cycle:
600,000 ON/OFF switching operations with rated load connected (equivalent to 10 years with one operation every 10 minutes)
NOTE
• Ask your nearest Yokogawa sales staff to replace relays.
• Do not replace relays by yourself, because the parts number of the relays to be used are different according to the relay specifications.
