Specifications
■ Ratings
Note: 1. Do not use an inverter output as the power supply. (Refer to
Safety Precautions for All Temperature Controllers.)
■ Characteristics
Note: 1. No reset function is incorporated by any E5C2 model with
ON/OFF control.
The reset function is used to correct offset for proportional
control. If there is an offset below the set value, turn the
reset adjustment clockwise.
2. A special Watertight Cover is used to achieve this degree of
protection (IP66, NEMA4). Refer to Y92A-
@@
N.
■ Connections
Connecting the Input
• Connect a thermocouple, the E52-THE@ Thermistor (replaceable
element) or a platinum resistance thermometer to terminals 1
(positive) and 2 (negative) on the E5C2 as shown in the following
illustration.
• On the E52-@@1D, the lead wires are thermocouple element wires,
making them difficult to solder because solder will not stick to them
easily. Remove the crimp terminal and polish the ends before
attempting to solder them.
Output
• If the load circuit is a heating control system, be sure to connect the
load to terminals 4 and 5. If the load circuit is a cooling control
system, be sure to connect the load to terminals 4 and 6.
• We recommend using an external relay to extend the electrical life
of internal relays when driving a large capacity load. This is
particularly important when the output relay is switched frequently
(e.g., with proportional control).
Power Supply
• If a single power supply is used for the E5C2 and the load, the
supply voltage of the power supply may vary greatly when the load
is open or closed if the capacity of the power supply is not large
enough. Make sure that the capacity of the power supply is large
enough so that the supply voltage range will be always from 90% to
110% of the rated supply voltage.
• The E5C2 operates at either 50 or 60 Hz.
