communication port, by using the special TZID-C configuration
P Limit of stroke counter or travel counter exceeded software.

If any of these disturbances occurs, an alarm is generated and in-
dicated as an error code on the built-in LC display, or reported as
a collective alarm via the digital output, which is already provided
by the basic TZID-C version.
Extended monitoring is possible via the communication port. The
most important process variables like the output signal in mA, the
position in %, the deviation and, last not least, troubles occurring
during operation are indicated as plain text in a special line.

Communication and special software for remote control and configuration
General
The TZID-C communication port allows for remote operation,
monitoring and configuration. T Z ID -C
L K S

The "HART “ Protocol is used for communication. Signals can
be tapped either locally at the connector or frequency-modulated
at any chosen point of the 4 ... 20 mA signal transmission. Com-
munication is done on line, without impairing operation. New pa-
rameter settings become active immediately after being

downloaded into the device, but have to be stored in the TZID-C
non-volatile memory with a special command.
The following equipment is needed for communication:
P a special connecting device
(LKS adapter or FSK modem)
P an off-the-shelf PC
(meeting special hardware requirements)

LKS adapter as a communication link
The LKS adapter is a connection solution which is both easy to
install and cost-saving. On the TZID-C side, a local communica- T a p a t th e 2 s o c k e ts o n th e F S K m o d e m
tion interface (LKS) is used. On the PC-side, a double sub-D jack T Z ID -C o r a t a n y c h o s e n p o in t
with a 9-pole and a 25-pole connector is used. The connector o f s ig n a l tr a n s m is s io n b e tw e e n
also accommodates an RS-232 interface converter for connec- th e T Z ID -C a n d th e s o u rc e .
tion to the PC.
The TZID-C can be configured via LKS without requiring that a 2 5 0 o h m s
4...20 mA signal is fed to it. As a result, this kind of configuration
can be performed in the workshop prior to commissioning. The T Z ID -C C O N TR A N S I S o u rc e
CPU is powered by the PC.

is o la tin g a m p lifie r C o n tra n s I a n d th e s o u rc e .
The FSK modem is used to establish digital frequency-modulated (C O N T R A N S I is H A R T ® c o m p a tib le )
communication (Frequency Shift Keying). The digital signal "0"
corresponds to 2.2 kHz, the digital signal "1" to 1.2 kHz. Tapping
is possible at any chosen point of 4...20 mA transmission, i.e.
directly on site at the TZID-C or in a remote place, e.g. at a PLS
T Z ID -C 4 ...2 0 m A C O N TR A N S I 4 ...2 0 m A S o u rc e
in the control room. Frequency-modulated communication re-
quires a circuit with a resistance of at least 250 ohms.
The FSM modem is available in 2 versions: with or without elec-
trical isolation. In conjunction with a special isolating amplifier,
e.g. Contrans I or Contrans I_remote, the modem with electrical T Z ID -C 4 ...2 0 m A C O N TR A N S I 4 ...2 0 m A S o u rc e
isolation is suitable for connection to a bus. Communication is
also possible with an intrinsically safe TZID-C, provided that the
modem itself is placed outside the hazardous area. If these capa- F S K b u s w ith is o la tin g a m p lifie r
bilities are not required, you can also use the cost-saving modem C O N T R A N S I w ith F S K c o n n e c tio n . F S K m o d e m

2.6 Operation Logic
Air pressure is being supplied to the output port as adjust bolt is being turned clock-wise
which will push the diaphragm. Pushed down diaphragm will disconnects the disc from the
stem. The set pressure level stays by transferring pressure to lower diaphragm, which will
result in balancing the adjust spring. In case of higher pressure than set level, the pressure
pushes diaphragm and pressure is released through the hole on the spring case.

2.7 Operation Logic
As supply pressure from regulator is connected to supply port and signal pressure is
connected to supply port, upper diaphragm (○
3 ) and diaphragm assembly will get pushed
down. As they are being pushed down, they push stem (○

7 ) and supply pressure will be
exhausted to output port. As output and supply pressure is equalized, stem (○

7 ) will be
moved to keep signal and output pressure the ratio of 1:1. If output pressure is higher than
signal pressure, diaphragm assembly will be raised, and output pressure in the exhaust ring
4 ) will be exhausted through exhaust port. The sensitivity of output pressure to signal
(○
pressure can be adjusted by setting adjust bolt (○

 No valve response to signal to a positioner.
 Please check if supply pressure is stable from regulator to positioner and/or to
volume booster.
 Please check if air pressure is being exhausted from positioner’s exhaust port.
 Please check if signal and exhaust ports of the volume booster are being cleared.
 Unstable valve operation when signal has been sent to a positioner.
 Hunting occurs when signal has been sent to a positioner.
 Please turn adjust screw counter-clockwise to reduce sensitivity.
 Slow valve operation after installing a volume booster.
 Please check if regulator pressure is too low.
 Please check if supply piping to the actuator has been blocked or clogged.
 Please check if there is any leakage.
 Please turn adjust screw clockwise to enhance sensitivity.

2.7 Operation Logic
When signal pressure is greater than setting pressure level, upper diaphragm(⑧) is being
pushed upward by signal pressure. As it gets pushed upward, vent port through lower
diaphragm(⑩) opens, so signal pressure pushes down lower diaphragm(⑩). Lower
diaphragm(⑩) pushes push-shaft(⑪) and push-shaft(⑪) pushes disk-seat(⑬), which
supply pressure will vent out through Lock Up Valve. Opposingly, when signal pressure is
less than setting pressure level, upper diaphragm(⑧) is being pushed downward and
lower diaphragm(⑩) will block signal-in port. ∅4 Ball(⑦) will be detached from upper
diaphragm(⑧) and the pressure will be exhausted.
