		For the E5ZE-8jjjjTCj (Thermocouple Input Models), the thermocouple
		inputs of the control points are insolated from each other.
1-3	Main Functions
Input Type		The E5ZE is connected to platinum resistance thermometers or thermocouples,
		depending on the model used. The type of temperature sensor is specified using
		the INPUT selector on the front panel of the Unit. The input values can be ad-
		justed using the input adjustment function.
CONTROL Outputs		The control outputs can be either voltage output or current output, depending on
		the model. The control period and direct/reverse operation can be specified us-
		ing the set values.
ALARM Outputs		A maximum of 2 alarm outputs are possible. There are 12 alarm modes that can
		be set for each alarm output according to set values. The outputs are compre-
		hensive output for all control points.
Output Limitations		The output values are limited by the following 2 limiters:
		• Output limiter
		• Output change rate limiter
		If an output value is outside the upper or lower limit for the output, the output will
		be limited to the preset upper or lower limit. The output change rate limiter limits
		the rate at which output values change per unit time.
Ramp		The ramp function is used to limit the control temperature (set point) from chang-
		ing rapidly. If the set point changes quicker than the preset rate, the rate of tem-

perature change will be limited to the preset rate, and the temperature will gradually change until it reaches the new temperature. The ramp can be set by the user.

Main Functions	Section 1-3
Control Adjustment	PID and fuzzy constants can be set by executing auto-tuning (AT). If an offset
	occurs during P or PD control, manual adjustment is possible using the manual
	reset function. Temperature turbulence caused by external disturbances can be
	suppressed and controlled using the fuzzy function.
Heater Burnout and SSR	Output short circuits caused by heater burnout or SSR failure can be detected.
Failure Detection
Control Method Selection	Control can be switched between ON/OFF control and the normal 2-PID control
	(with 2 degrees of freedom). Manual operation is also possible.
Memory Banks	The memory banks store different sets of set values for the control points. There
	are 8 memory banks for each control point. Memory banks allow the set values
	for a control point to be changed as a group rather than resetting them individu-
	ally. Use the external contact inputs or communications to designate the re-
	quired memory bank.

Observe the following precautions when operating the selectors and switch.

•Always make sure the power is OFF before changing the selectors and switch.

•Use a small flat-blade screwdriver to change the selector and switch settings, and be sure that the selectors are correctly positioned.

2-3-1 UNIT Selector

UNIT INPUT

When serial communications are being used, the UNIT selector must be set so that the host device can recognize the E5ZE unit number.

When more than one E5ZE Multipoint Temperature Controller is being used with

RS-422 or RS-485 communications, set a different unit number for each E5ZE.

•The selector settings 0 to F correspond to unit numbers 00 to 0F. The factory setting of 0 corresponds to unit number 00.

2-5 Power Supply and Input Wiring

2-5-1 Terminal Block

The input terminal block has been designed with a removable terminal-screw panel. When connecting the power supply or temperature sensor, the terminalscrew panel can be conveniently removed before wiring.

•To remove the terminal-screw panel, loosen the two screws alternately indicated by A in the above diagram.

•To mount the terminal-screw panel, insert it into the terminal block and secure the two screws (A) alternately.

•If the terminal block has been removed from the E5ZE Thermocouple Input Model, when reconnecting make sure that the E5ZE’s lot number and serial number are the same as those of the terminal block. Accuracy cannot be guaranteed for a Unit that has been connected to a terminal block with a different lot number and serial number.

2-5-2 Wiring

•Always turn OFF the power supply before performing any wiring.

•Be sure to check polarity when connecting the power supply and temperature sensor.

•Wire the power supply cables separately from the temperature sensor cables to prevent noise interference.

•Use either crimp terminals or solder the wire ends when wiring terminals.

•Tighten the terminal screws.

•Wire the power lines close to the terminal block to prevent external force being exerted on the power lines from torsion or weight.

•Do not use the terminals that are marked “Don’t use.”

•Do not bend the crimp terminals after they have been connected and the screws have been tightened.
