Error Displays (Troubleshooting)

When an error occurs, the No. 1 display or No. 2 display shows the error code.

Take necessary measure according to the error code, referring the following table.

Display

Action

Operation

s.err

Input error

The input value exceeded the control

range.*

The input type is not set correctly.

The sensor is disconnected or short-

circuited.

The sensor is not wired correctly.

The sensor is not wired.

* Control Range

Temperature resistance

thermometer or thermocouple input:

SP Lower Limit - 20°C to SP Upper

Limit + 20°C

(SP Lower Limit - 40°F to SP Upper

Limit + 40°F)

ESIB input:

Same as specified input range.

Analog input:

Scaling range -5% to 105%

Check the wiring for input to be sure

it is wired correctly, not broken, and

not shorted. Also check the input

type.

If there are no problems in the wiring

or input type settings, cycle the

power supply.

If the display remains the same,

replace the Digital Temperature

Controller.

If the display is restored to normal,

then the probable cause is external

noise affecting the control system.

Check for external noise.

Note: For a temperature resistance

thermometer, the input is

considered disconnected if

the A, B, or B line is broken.

After the error occurs and it is

displayed, the alarm output will

operate as if the upper limit was

exceeded.

If an input error is assigned to a

control output or auxiliary output, the

output will turn ON when the input

error occurs.

The error message will appear in the

display for the PV.

Note: 1. The heating and cooling

control outputs will turn

OFF.

2. When the manual MV, MV

at stop, or MV at error is

set, the control output is

determined by the set

value.

[[[[

Display

range

exceeded

Below -1,999

This is not an error. It

is displayed when the

control range is wider

than the display

range and the PV

exceeds the display

range. The PV is

displayed for the

range that is given on

the left (the number

without the decimal

point).

Control continues and operation is

normal.

The value will appear in the display

for the PV.

Refer to the E5

@D Digital

Temperature Controllers User’s

Manual (Cat. No. H224) for

information on the controllable range.

e333

A/D

converter

error

There is an error in the internal

circuits.

After checking the input error, turn

the power OFF then back ON again.

If the display remains the same, the

controller must be repaired.

If the display is restored to normal,

then a probable cause can be

external noise affecting the control

system. Check for external noise.

The control outputs, auxiliary

outputs, and transfer outputs turn

OFF.

(A linear voltage output will be

approx. 0 mV.)

e111

Memory

error

There is an error in the internal

memory operation.

First, cycle the power supply.

If the display remains the same, the

controller must be repaired.

If the display is restored to normal,

then a probable cause can be

external noise affecting the control

system. Check for external noise.

The control outputs, auxiliary

outputs, and transfer outputs turn

OFF.

(A linear voltage output will be

approx. 0 mV.)

ffff

Overcurrent

This error is displayed when the peak

current exceeds 55.0 A.

Control continues and operation is

normal.

The error message will appear for the

following displays.

Heater Current Value 1 Monitor

Leakage Current Value 1 Monitor

ct1

lcr1

HB or HS

alarm

If there is a HB or HS alarm, the No.

1 display will flash in the relevant

setting level.

The No. 1 display for the following

parameter flashes in Operation Level

or Adjustment Level.

Heater Current Value 1 Monitor

Leakage Current Value 1 Monitor

However, control continues and

operation is normal.

----

Ambient

temperature

out of

monitor

range

Ambient temperature exceeded the

following display range.

Temperature unit =

°C: −30 to 75°C

Temperature unit =

°F: 10 to 171°F

Make sure that the ambient

temperature of the Controller is

within the rated range. The following

factors may be present. Check

them.

• The Controller is subjected to

heat radiated from heating

equipment.

• The Controller is subjected to

direct sunlight.

• The Controller is subjected to

icing or condensation.

Control continues and operation is

normal.
