Ordering Information

■ List of Models

Note: 1. Terminal Units are required for wiring. Purchase separately.

2. When connecting the load of the controlled system, heat control output or cool control output can be allocated to the control output or auxiliary

output. When connecting a recording device or Digital Panel Meter, transfer output can be allocated to control output or auxiliary output 3 or 4 of
analog output models.

3. When using the heater burnout alarm, purchase a Current Transformer (CT) separately.

4. When using heating and cooling control functionality, the auxiliary output will be either heating control output or cooling control output.

5. Analog input and infrared temperature sensors (ES1A-A) can also be used with thermocouple models.

Note: 1. When using 2 or more E5ZNs mounted side-by-side, use the E5ZN-SCT18S-500 for the second and subsequent Units. When using

E5ZNs separately, be sure to use the E5ZN-SCT24S-500.

2. Two End Plates are provided with E5ZN-SCT24S-500 Terminal Units. When mounting to a DIN track, be sure to mount End Plates on

both sides.

Installation

■ Connection Diagrams

• Voltage output (control output) is not electrically isolated from internal circuitry. Therefore, when using grounded thermocouples, do not ground

control output terminals. (Doing so may result in temperature measurement errors due to unwanted current paths.)

• There is basic insulation between the power supply inputs and outputs for this product. If reinforced insulation is required, connect the input and

output terminals to equipment without any exposed charge-carrying parts, or to equipment with basic insulation sufficient for the maximum oper­ating voltage of the power supply and the inputs and outputs.

■ Examples of Functions

Using as a Temperature Input Signal
Converter

Transfer Output Types

• The ten types of data shown below can be allocated for transfer

output using the control output 1 allocation, control output 2 alloca­tion, auxiliary output 3 allocation, and auxiliary output 4 allocation
(initial setting level).

• Transfer output is supported by analog output models only.

Note: Control outputs 1 and 2 use current output and auxiliary out-

puts 3 and 4 use linear voltage output.

Transfer Output Scaling

• The range set by the transfer output upper limit and transfer output

lower limit (initial setting level) can be scaled to the output range for
the transfer output (4 to 20 mA DC or 0 to 20 mA DC for control out­puts 1 and 2, and to 1 to 5 VDC or 0 to 5 VDC for auxiliary outputs
3 and 4).

• The scale can be expanded by setting a small range between the

transfer output upper and lower limits. Reverse scaling can be per­formed by setting the transfer output upper limit to a value smaller
than the transfer output lower limit. The following figure shows a
scaling example where the heating control MV transfer output is
scaled to 1 to 5 VDC.

Example: Scaling to 1 to 5 VDC

Reading Temperatures for Multiple
E5ZN Units

With conventional models, if the present temperature is read from
multiple Temperature Controllers using host communications, there
are time differences in the process temperatures read from each
Temperature Controller, making it difficult to obtain concurrent data.

With the E5ZN, the PV hold function can be used to ensure that the
data is concurrent to within 500 ms.

PV Hold

The PV hold function temporarily stores the present temperature for
that moment as the PV hold value, when the "PV hold" operation
command sent by host communications is received. (See fig. 1.)

Fig. 1

Note: 1. PV hold values are overwritten every time the "PV hold" op-

eration command is executed. Once the PV hold values
have been read for channels that require simultaneous
reading of present temperatures, execute the next "PV hold"
operation command.

2. The "PV hold" operation command cannot be executed and

the "PV hold value" cannot be read from the E5ZN-SDL Set­ting Display Unit.

3. When the power is turned OFF, the PV hold values change

to 0.

Other terminals: AWG 28 to 16
(Length of exposed part: 6 to 8 mm)

8. Do not connect anything to unused terminals.

9. Ensure that the rated voltage is reached within 2 seconds of turn-

ing power ON.

10.Allow 30 seconds’ warm-up time.

11.Install the product as far away as possible from devices that gen-

erate strong, high-frequency noise and devices that generate
surges.

12.Keep wiring separate from high-voltage power lines or power lines

carrying large currents. Do not wire in parallel with or together
with power lines.

13.Install switches or circuit-breakers so that the user can turn the

power OFF immediately, and indicate these accordingly.

14.Do not use the product in the following locations:

• Locations subject to dust or corrosive gases (in particular, sul-

fide gas and ammonia gas)

• Locations subject to freezing or condensation

• Locations exposed to direct sunlight

• Locations subject to vibrations or shocks

• Locations subject to exposure to water or oil

• Locations subject to heat radiated directly from heating equip-

ment

• Locations subject to intense temperature changes

15.When the Terminal Unit is separated from the Temperature Con-

troller, under no circumstances touch the electrical components
or apply shock to the Temperature Controller.

16.Do not use solvents to clean the product. Use commercial alco-

hol.

17.After wiring is completed remove the dust-protection label to allow

proper heat dissipation.

18.When mounting the Temperature Controller to the Terminal Unit,

make sure that the hook on the side of the Temperature Controller
facing the Terminal Unit is inserted properly.

19.Install the DIN track vertically.

■ Correct Use

Service Life

Use within the following temperature and humidity ranges:

• Temperature: –10 to 55×C (with no icing or condensation)

• Humidity: 25% to 85%

I-142 Modular Temperature Controller E5ZN

If the product is installed inside a control panel, the temperature
around the product (and not the temperature around the control
panel) must be kept below 55×C.

With electronic devices like the E5ZN, the service life will depend not
only on the number of switching operations performed by the relay
but also on the service life of the internal electronic components. The
service life of these components depends on the ambient tempera­ture; it will be shorter if the ambient temperature is high, and longer if
the ambient temperature is low. For this reason, the service life of the
product can be lengthened by keeping the inside of the E5ZN at a
low temperature.

If several Units are mounted side-by-side or are arranged vertically,
the heat generated may cause the internal temperature of the Units
to rise, reducing service life. To prevent this, take steps to ensure that
the Units are cooled, such as installing fans.

Ensure, however, that the terminals are not also cooled, otherwise
correct temperature measurement will not be possible.

Measurement Accuracy

When extending the lead wires for thermocouples, use a compensat­ing conductor appropriate for the type of thermocouple used.

When extending the lead wires for platinum resistance thermome­ters, use lead wires with a low resistance, and make the resistance in
the 3 lead wires equal.

Mount the E5ZN horizontally.
If significant errors occur, check that input compensation has been

set correctly.

Waterproofing

The enclosure ratings are given below. Parts for which the enclosure
rating is not clearly indicated, and parts with IP@0 ratings (where @
is not 0) do not have waterproof specifications.

• Temperature Controller: IP00

• Terminal Unit: IP00

Mounting and Dismounting

• To mount using a mounting track, first hook part A (see below) onto

the track and then push down on part B.

• To dismount, insert a flat-bladed screwdriver into part C, pull the

hook down, and then lift the bottom part of the E5ZN upwards.

• Mount the E5ZN at least 30 mm away from other devices to ensure

easy mounting and dismounting.

Note: Refer to the following manual for precautionary information and other information necessary to use the E5ZN: E5ZN Temperature Controller

Operation Manual (Cat. No. H113).
