BANK and three ING terminals are used to select the current memory bank as
explained following the table. As the three ING terminals are internally con-
nected, it does not matter which is used. Do not connect anything to the unused
terminals.
Caution CTRL

G terminals are common ground terminals connected together internal-
ly. Do not short-circuit the CTRL

CN302
Terminal Assignments The following table shows the terminal assignments for CN302. All alarm and
error outputs are open-collector outputs.
Note Open-collector outputs are not protected from excessive current flow; be sure to
wire them correctly to protect internal circuits from damage.
ALARM1G and ALARM2G are the emitters and ALARM1 and ALARM2 are the
collectors for alarm 1 and alarm 2, respectively. The HB alarm output goes ON
when the detected current falls below the set heater current. The HS alarm out-
put goes ON when there is a current flow of 0.5 A or more on the CT when the
control output of the E5ZD is OFF. The error output goes ON when an abnormal-
