1. Installation Precautions

CautionThis instrument is intended to be used under the following environmental conditions(IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of -5 to 55 (23 to 131 )that does not change rapidly, and no icing• An ambient non-condensing humidity of 35 to 85%RH• No large capacity electromagnetic switches or cables through which large current is flowing• No water, oil or chemicals or where the vapors of these substances can come into
direct contact with the unit
• If this instrument is installed within a control panel, the ambient temperature of the unit
- not the ambient temperature of the control panel - must be kept to under 55 (131 ).
Otherwise the life of electronic parts (especially electrolytic capacitors) of the unit will
be shortened.
Note: Avoid setting this instrument directly on or near flammable material eventhough the case of this instrument is made of flame-resistant resin.

2. Wiring Precautions

Caution• Do not leave wire remnants in the instrument, because they could cause a fire and/or amalfunction.
• When wiring terminals, use a solderless terminal with an insulation sleeve in which an
M3 screw fits.
• Tighten the terminal screw using the specified torque.
If excessive force is applied to the screw when tightening, the screw may be damaged.
• This instrument has no built-in power switch, circuit breaker or fuse. It is necessary to
install them near the instrument.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)• For wiring of AC power source, be sure to use exclusive terminals as described in thismanual. If AC power source is connected to incorrect terminals, the unit will burn out.
• For a 24V DC power source, do not confuse polarity.
• Do not apply a commercial power source to the sensor connected to the input terminal nor
allow the power source to come into contact with the sensor, as the input circuit may burn out.
• Use a thermocouple, compensating lead wire and 3-wire type RTD according to thesensor input specifications of this unit.
• When using DC voltage and current input, do not confuse polarity when wiring.
• Keep the input/output wires and power line separate.

3. Operation and Maintenance Precautions

Caution• Do not touch live terminals. This may cause electric shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal andcleaning. Working on or touching the terminal with the power switched ON may result
in severe injury or death due to Electric Shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)• As the display section is vulnerable, do not strike or scratch it with a hard object or
put pressure on it.

Setup should occur before using this unit, to set (or select) an Input range, Scaling low limit
value, Scaling high limit value, Alarm type, etc. according to the users’ conditions.
Setup is conducted in the CH1 function group, CH2 function group (SE2 A) and Special
function group.
Refer to the default values in (Table 6-1) to (Table 6-3).
If the users’ specifications are the same as the default value of the instrument, or if setup
has already been completed, it is not necessary to set up the instrument. Proceed to
Section “7. Alarm settings”.

6.2 Basic Operation of Setup
Setup is conducted in each function group.
For the SE2 A, CH1 and CH2 should be set respectively.
(E.g.) To enter the CH1 function group for the SE2VA:(1) Press the
key 3 times in the RUN mode. (Fig. 6.2-1)(2) Press the
key while CH1 function group characters are indicated.
(Fig. 6.2-2)(3) The unit moves to the “Input range” selection item in CH1 function group.
To set (or select) each item, use theorkey, and register the value
with thekey. (Fig. 6.2-3)
If thekey is pressed at the last setting item of each group, the unit
reverts to the RUN mode.

Automatically measures and controls brightness of the displays

The setting data is backed up in the non-volatile IC memory.
The CPU is monitored by a watchdog timer, and if an abnormal
status is found on the CPU, the instrument is switched towarm-up status, turning all outputs OFF.
Available only for the SE2EA and SE1EA.
This detects the temperature at the connecting terminal between
the thermocouple and the instrument, and always maintains it at

10. Troubleshooting
10.1 Indication

ProblemPresumed Cause and Solution

The Input display is
flashing "
" or
"
".
The input value does notchange.

• The sensor may be burnt out.
Change each sensor.
• Check whether the sensor is securely connected to the
input terminals of the instrument.
Ensure that the sensor terminals are securely connected tothe input terminals of the instrument.
• Check the input signal source.
• Check whether polarity of thermocouple or compensating
lead wire is correct.
Check whether codes (A, B, B) of the RTD match the
instrument terminals.
Ensure that they are wired properly.
• Check whether the sensor input and temperature unit( / ) settings are correct.
Ensure that sensor type and temperature unit ( / ) are set
properly.
• Check whether the sensor correction value is suitable.
Set it to a suitable value.
• AC leaks into the sensor circuit.
Use an ungrounded type sensor.
• There may be equipment that interferes with or makes
noise near the unit.
Keep equipment that interferes with or makes noise awayfrom the unit.

The indication of the
Input display is irregularor unstable.

10.2 Key Operation
ProblemPresumed Cause and Solution

Settings are not possible. • “Lock 1” or “Lock 2” is selected in [Set value lock].
Select “Unlock”.
10.3 Operation
Problem
Alarm output does notturn ON.

Alarm output does notturn OFF.

Presumed Cause and Solution• Check whether alarm value and alarm delay time havebeen set to suitable values.
• Check whether Alarm type and Alarm Energized/
De-energized have been selected correctly.
• Check whether alarm value and alarm hysteresis havebeen set to suitable values.
• Check whether Alarm type and Alarm Energized/
De-energized have been selected correctly.
• Check whether Alarm HOLD function is working.
To turn the alarm output OFF while Alarm HOLD function is
working, turn the power to the unit OFF.
