OUTPUT ASSIGNMENTS
Signals available as allocated outputs are the control output
(heat), control output (cool), alarm 1, alarm 2, alarm 3, LBA. The
auxiliary outputs of the Process Controller cannot be used as
control outputs. The E5CK-T does not have a heater burnout
alarm (HBA).
Control output (heat), control output (cool), alarm 1, alarm 2,
alarm 3, LBA, error 1 (input error), and error 2 (A/D converter
error) output functions are available. These functions are
assigned to control outputs 1 and 2 and auxiliary outputs 1 and 2.
The assignment destination of each output function is restricted.
Refer to the tables provided under the headings, Standard
Models and Position-Proportionate Models.

With control output (cool), the conditions for switching from
standard control to heating and cooling control are reached
when the output function is assigned at the cooling side during
heating and cooling control.
In other words, heating and cooling control is carried out when
control output (cool) is assigned, and standard control is carried
out when output is not assigned.
LBA
The LBA (loop break alarm) function is available when it is
assigned as an output. The LBA function is not available when a
memory or A/D converter error results.
LBA is a function for determining that an error has occurred
somewhere on the control loop and outputting an alarm when the
process value does not change with the manipulated variable at
a maximum or minimum state. Accordingly, the LBA function can
be used as a means for detecting a malfunctioning control loop.
