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
• When installing this unit within a control panel, take note that ambient temperature ofthis unit must not exceed 55 (131 ). Otherwise the life of electronic components(especially electrolytic capacitor) may be shortened.
Note • Do not install this instrument on or near flammable material even though the case ofthis instrument is made of flame-resistant resin.

2. Wiring precautions

Caution• Do not leave bits of wire in the instrument, because they could cause a fire and malfunction.
• When wiring terminals, use ferrules with an insulation sleeve and crimping pliers madeby Phoenix Contact GMBH & CO. applicable to terminals.
• Tighten the terminal screw using the specified torque.
If excessive force is applied to the screw when tightening, the screw or case may bedamaged.
• 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 when wiring.
• 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 system 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 wire (TC, RTD, etc.), power line and load wire away from one another.

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 or touching the terminal with the power switched ON may result insevere 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 orpress hard on it.

Attached function• Power failure countermeasure:
The setting data is backed up in the non-volatile IC memory.
• Self-diagnosis:
The CPU is monitored by a watchdog timer, and if an abnormal status is found on
the CPU, the unit is switched to warm-up status with all outputs off.
• Cold junction compensation:
Available only for the SAEA.
This detects the temperature at the connecting terminal between the thermocouple andthe instrument, and always maintains it at the same status as if the reference junction
is at 0 (32 ).

10. Troubleshooting
10.1 Indication
Problem
The Input display is
flashing "
" or
"
".

Presumed cause and solution• 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 connectedto the 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 agree with the
instrument terminals.
Ensure that they are wired properly.
The indication of the Input • Check whether the sensor and input specifications of thedisplay is abnormal orunit are correct.
unstable.
Ensure that sensor type and input specifications of the unit
matches.
• 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 noiseaway from the unit.

10.2 Key operation
Problem
Setting is impossible.

10.3 Operation
Problem
Input value does notchange.

Alarm output is notturned ON.
Alarm output is notturned OFF.

Presumed cause and solution• “Lock” is selected during Set value lock selection.
Select “Unlock”.

Presumed cause and solution• The sensor may be out of order. Change the sensor.
• Check whether input and output wires are securely
connected to the I/O terminals of the instrument.
Ensure that input and output wires are securely connectedto the I/O terminals.
• Check whether the wiring of input and output is correct.
• Check if set values such as Alarm value, Alarm type, Alarm
action Energized/De-energized, Alarm hysteresis and Alarm
action delay timer have been set suitably.
Set them to suitable values.
• Check if set values such as Alarm value, Alarm type, Alarm
action Energized/De-energized, Alarm hysteresis and Alarm
action delay timer have been set suitably.
Set them to suitable values.
• Check if Alarm Hold function is working.
To turn the alarm output OFF while alarm Hold function is
working, turn the power OFF.
