GENERAL
The SALD mV and temperature alarm unit receives a mV DC, thermocouple or
RTD (resistance temperature detector) input directly, compares this input with an
alarm set point, and outputs an alarm contact signal. The input has one or two
absolute-alarm outputs.
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*1 is used for setting the SALD parameters.
On the SALD model with display setter (SALD-x04), input indication (engineering
unit) can be displayed and alarm set points can be displayed / set on the front
panel.

Explanation of Input processing block
• A/D conversion: Performs A/D conversion on input signals.
• Normalization:
Calculates the value required for each of input.
• Burnout:
SALD-xx0: Action (UP/DOWN/OFF) can be set by parameter.
SALD-xx4: Action (UP/DOWN/OFF) can be set using setting jumper on the main
board.
• Temperature unit conversion:
When input signal is thermocouple or RTD, temperature unit (°C or K) can be set.
• Input range:
When input signal is mV DC, input range can be set (See Scaling below.)
• Scaling:
When input signal is mV DC, scaling is possible for the range set at input range.
The value after scaling (or, when the bias function is used, the value obtained by
adding bias to this value) becomes PV1.
Setting of INPUT1 L_RNG, INPUT1 H_RNG, SCH1, SCL1 and DP1
(Default: 0.0 to 100.0)
<Setting Method>
The following is the example when measuring range of 10.0 to 80.0 mV is scaled to
1000 to 20000.
(1) Set the measuring input range at the parameters INPUT1 H_RNG and INPUT1
L_RNG.
(Example: INPUT1 L_RNG=10.0, INPUT1 H_RNG=80.0)
(2) Set the input decimal point position matched to the unit system actually in use at
DP1.
(Example:DP1=”#####”, DP1=0)
(3) Set the measuring scale range at the parameters SCH1 and SCL1.
(Example: SCL1=1000, SCH1=20000)

• 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.
• PV1:
The value obtained by adding bias to the scaling value.

Alarm Processing Function
SET POINTn (SPn) can also be set using display setter on the front panel.
Explanation of Alarm detection block
The following "n" indicates "1" or "2".
• 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.
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 about 3 seconds after power ON.

Replacement of Fuse
When the fuse has blown 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
6-5.
(2) When installing a new fuse, use a fuse with the correct rating. Fasten the cap
securely.
Figure 6-5 Replacement of Fuse
6.5
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 01B04K02-02E) and capacitor to be used are different
according to the power supply specifications.

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.
