Operation Via Trovis-View; Initialization - Samson 3787 Mounting And Operating Instructions

4.5 Operation via TROVIS-VIEW

In addition to using the fieldbus configura-
tion or operating system via fieldbus com-
munication, the positioner can also be oper-
ated with SAMSON's TROVIS-VIEW user in-
terface via the serial port integrated in the
device.
You can configure all the parameters using
the device module intended for the TROVIS-
VIEW software.
For connection of the positioner to the serial
port of the PC, you will need an adapter
(order no. 1400-7700).
You can either connect the power supply to
the device using a fieldbus segment, or by
connecting a voltage source (9 to 32 V) to
the bus terminals on the device.
When the device is connected to a Founda-
tion Fieldbus bus segment, you can simulta-
neously operate TROVIS-VIEW and the
fieldbus system without any restrictions.

4.5.1 Initialization

When you initialize the device via the
fieldbus system or TROVIS-VIEW, the initial-
ization routine is started over the parameter
SELF_CALIB_CMD.
You can select an initialization routine
based on either the nominal range or maxi-
mum range by setting the parameter
INIT_METHOD accordingly.
During initialization based on nominal
range, the following parameters must be set:
VALVE_TYPE
Option: Rotary or linear actuator
MOUNTING_POSITION
Positioner alignment to actuator (for li-
near actuator).
ATTACHMENT
Defines the attachment of the positioner
(Select: Namur/integrated).
RATED_TRAVEL
Rated travel or nominal angle of the
valve
ACTUATOR_VERSION
Determines whether the actuator is single
acting or double acting.
Options for linear actuator with NAMUR at-
tachment:
TRANSM_LENGTH
Specifies the length of the lever
TRANSM_PIN_POS
Specifies the position of the pin on the
lever.
Options for linear actuator with integrated
attachment:
TRANSM_CODE
Determines the size of the travel pick-off
for integrated attachment.
Options for rotary actuator:
TRANSM_CODE
Determines the cam disk used.
During initialization, the following par-
ameters are determined:
ACT_FAIL_ACTION
Fail-safe action of the actuator when the
supply air fails.
ACT_STROKE_TIME_DEC
Minimum transit time to CLOSED position
ACT_STROKE_TIME_INC
Minimum transit time to OPEN position
