Set Point 1 Setting: sp 1
Use the Down and Up Keys to set the set point 1. It is possible to set
the value regardless of whether the set value presently selected is
on SP0 or SP1.
E5CJ
The set point can be selected by opening or short-circuiting the
EV1 terminals (terminals 13 and 14).

E5AJ/E5BJ/E5EJ
The set point can be selected by opening or short-circuiting
the EV1 terminals (terminals 17 and 20). In the case of the
E5BJ, however, the terminals 16 and 17 of which should be
opened or short-circuited instead.

Heater Current Value Display: ct
The display range is 0.0 to 55.0 A. FFFF will be displayed if the cur-
rent exceeds 55.0 A. When the control output is ON, the current
flowing to the heater is measured and displayed. If the control output
is, however, turned ON for less than 190 ms, the current flow will not
be measured and the current previously measured will be dis-
played.
Heater Burnout Alarm Value Setting: hb
The current value to detect heater burnout can be set within a range
of 0.0 to 50.0 A.
The current value is factory-set to 0.0 A. Check the normal heater
current and the current at the time of heater burnout from the heater
current value display, and set the set value to the mean value of the
current values (i.e., set value = (normal current value + heater burn-
out current) B 2).
If the difference between the normal heater current and heater burn-
out current is small, heater burnout detection will not be stable. For
stable detection, the difference in current must be 1.0 A minimum if
the heater input is less than 10.0 A and 2.5 A minimum if the heater
input is 10.0 A or more.
Note: 1. Do not allow a current exceeding 50 A to flow in the CT;
the maximum continuous heater current is 50 A.
2. Set the value to 0.0 A if the heater burnout alarm is not
used, in which case the alarm will not function at all.
