1. EN6000B1/B2-Digital Controller/Dual-loop Digital
Controller
EN6000B1/B2 is a single/dual-loop
proportional-integral-differential controller, with seven choices of
external dimensions.
(1) Product Features
¡ó Auto-Tuning (AT)
The AT function determines automatically the best method to
calculate the optimum PID parameters and makes it easy to balance the system
and suppress the disturbance quickly.
¡ó Program control
EN6000B1 have 8 groups (128 segments) of program control curves, which make
it possible to control the temperature rising or dropping at any rate. Each
segment of curves could set different PID control parameters and different
output amplitude limits. And there are 8 choices of PID control parameters
and 8 choices of output amplitude limits.
Corresponding, EN6000B1 could execute such programmable operating commands
as Jump, Run, Pause and Stop. And the
program is allowed to be revised at any moment during the program control
and operation.
User can select handling mode for power-failure/power-on accidents, which
could eliminate effectively the influence on program control resulted from
unexpected power failure and make program execution more effective.
User can use external switch to execute such operations as Run,
Pause and Stop and to implement interlock,
synchronized start-up and synchronized operation, which makes it much
convenient to manually operate. And 4 program signal outputs could be used
to interconnect with other equipments.
¡ó Flexible alarm and retransmission
Alarm types: upper limit alarm, lower limit alarm, upper deviation alarm,
lower deviation alarm, inner deviation alarm, outer deviation alarm,
overrange alarm and so on, and the standby alarm could be set.
User can select PV, SV, OP1, OP2 or valve position signals to be transmitted
and retransmission signals could be set to be 0-10mA, 4-20mA, 0-20mA current
via software.
¡ó Convenient and fast communication
EN6000B1 could be provided with an RS485 port for communications. One or
multiple (max. 100) EN6000B1 and one PC could form a computer monitor system
like a field bus system. On host computer user can implement all operations
of EN6000B1 via RS485 port and ENVADA communication protocol, such as
Read measure values and setting values in real time,
Set parameters, Switch M/A, Adjust
manual output value, Start/Run/Stop program. User has 4
choices of the communication rate (baud rate) between 2400 and 19200bps.
ENVADA can provide users with standard communication software on PC (host
computer) or modify the communication software according to the
communication protocol of users.
¡ó Advanced parameter protection
EN6000B1 is provided with the function of multilevel parameter protection to
avoid any illegal operation.
