CONFIGURATION PARAMETERS

OPERATION CYCLE

PV Indication

(Red)

SV Indication

(Green)

PV AND SV INDICATION: The status display shows the

present value of PV (Process Variable). The parameter

display shows SV (Set Variable).

The status display shows “---

------

----

-“ whenever PV exceeds the

maximum range or there is no signal at the input. In case of

hardware error the status display will show Ern

ErnErn

Ern, where n is

the error code.

avto

CONTROL MODE: YES indicates automatic control mode

(closed loop, PID or ON/OFF). NO indicates manual control

mode (open loop). Bumpless transfer from auto ↔ to

manual mode is available. If in doubt program YES.

PV Indication

(Red)

MV Indication

(Green)

MANIPULATED VARIABLE VALUE (MV): The upper display

shows PV value and the lower display shows the percentage

of MV applied to the control output. When in manual control

the MV value can be manually changed. When in auto mode

the MV value can only be viewed.

To distinguish the MV display from the SV display, the MV

is shown flashing intermittently.

RAMP AND SOAK PROGRAM SELECTION: Selects the

ramp and soak program to be executed (7 programs

possible). Refer to chapter 7 for R&S description.

CONTROL ENABLE: YES means that the control output

and alarms are enabled and NO means they are disabled.

AUTO TUNING CYCLE

AUTO-TUNE: YES enables the auto tuning of the PID

parameters and NO disables it.

PROPORTIONAL BAND: Percentage of maximum input

span. Select zero for ON/OFF control.

INTEGRAL RATE: Integral time constant in repetitions per

minute (Reset).

DERIVATIVE TIME: Derivative time constant, in seconds.

CYCLE TIME: PWM period in seconds. Can only be viewed

if proportional band is other than zero.

SOFT START: Time in seconds during which the controller

limits the MV value progressively from 0 to 100 %. It is

enabled at power up or when the control output is

activated. If in doubt set zero.

RAMP AND SOAK TOLERANCE: maximum deviation

between PV and SV. Whenever this deviation is exceeded

the time counter is halted until deviation lowers to within the

tolerance. Set zero to disable this function.
