Digital Controller

E5AK/E5EK

■ Parameter Initialize

Parameter initialization sets all parameters to default values except

for the input type, scaling upper limit, scaling lower limit, decimal

point, and

°C/°F selection parameters.

■ Output Assignments

Signals available as allocated outputs are the control output (heat),

control output (cool), alarm 1, alarm 2, alarm 3, LBA, and HBA. The

auxiliary outputs of the Digital Controller cannot be used as control

outputs.

Control output (heat), control output (cool), alarm 1, alarm 2, alarm 3,

LBA, error 1 (input error), error 2 (A/D converter error), and error 3

(RSP input 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 may be

restricted. Refer to the following table.

Standard Models

In other words, heating and cooling control is carried out when con-

trol output (cool) is assigned, and standard control is carried out

when output is not assigned.

Position-proportional Models

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 some-

where 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.

Output function

Assignment

destination

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.
