3.3.1 Electrostatic discharge (ESD) considerations

Important Note: To minimize hazards and ESD risks, maintenance procedures not
requiring power to the analyzer should be performed with power removed.

Delicate internal electronic components can be damaged by static electricity, resulting in
degraded instrument performance or eventual failure. The manufacturer recommends
taking the following steps to prevent ESD damage to your instrument:

• Before touching any instrument electronic components (such as printed circuit cards
and the components on them) discharge static electricity from your body. This can be
accomplished by touching an earth-grounded metal surface such as the chassis of an
instrument, or a metal conduit or pipe.

• To reduce static build-up, avoid excessive movement. Transport static-sensitive
components in anti-static containers or packaging.

• To discharge static electricity from your body and keep it discharged, wear a wrist
strap connected by a wire to earth ground.

• Handle all static-sensitive components in a static-safe area. If possible, use anti-static
floor pads and work bench pads.

Installation

3.4 Electrical installation

DANGER
Electrocution hazard. Only qualified personnel should conduct the installation
tasks described in this section of the manual.

DANGER
Electrocution hazard. Always install a ground fault interrupt circuit (GFIC)/ residual
current circuit breaker (rccb) with a maximum trigger current of 30 mA. If installed
outside, provide overvoltage protection.

If installed outdoors, provide overvoltage protection between the power and the sc1000
controller. Make sure the data and power cables do not cause tripping and do not contain
any sharp bends. Refer to Figure 7 for housing breakout information.

High-voltage wiring for the controller is conducted behind the high voltage barrier in the
controller enclosure. The barrier must remain in place unless a qualified installation
technician is installing wiring for power, alarms, or relays. See Figure 9 for barrier
removal information.

The instrument can be wired for line power by hard-wiring in conduit or by wiring to a
power cord if allowed by local electrical code. A local disconnect designed to meet local
electrical code is required and must be identified for all types of installation.

Do not connect the electrical power supply to the AC power until the sc1000 controller
has been fully wired, fused, and the high voltage barrier and probe module cover have
been replaced.

3.4.1 Installation in hard-wired applications

In hard-wired electrical applications, the power and safety ground service drops for the
instrument must be 18 to 12 AWG. A sealing-type strain relief must be used to maintain
the IP65 environmental rating. See Figure 6 for strain relief and conduit opening sealing
plug assembly. See Figure 13 for wiring information.

Note: There is no on/off switch to disconnect the probe module from AC Power.

16

3.4.2 Installation using a power cord

A sealing-type strain relief to maintain the IP65 environmental rating and a power cord
less than 3 meters (10 feet) in length with three 18-gauge conductors (including a safety
ground wire) can be used, see Section 9 on page 129. See Figure 6 for strain relief and
conduit opening sealing plug assembly. See Figure 14 on wiring information.

3.5 DIN rail expansion modules

CAUTION
The expansion modules for control cabinet installation use the 24 VDC power
supply in the control cabinet. Make sure that the correct power supply is provided.
Install a residual current circuit breaker. The modules have an environmental rating
of IP20 and must always be mounted in an enclosure suitably rated for power and
environment.

The sc1000 controller can be expanded with DIN rail expansion modules.

The following DIN rail module options can be installed:

• Base module (for connecting power, sc1000 network and display module)–The base
module is required for the installation of expansion modules on the control cabinet.

• Relay card with 4 relays

• mA output card with 2 outputs

• mA input card with 2 inputs (analog or digital)–One base module can provide up to

2000 mA of power to the other modules connected to it on the DIN rail.

The total number of modules that can be connected together is limited by the power
supply from the base module. Up to 13 communication modules can be attached to each
base module. When more than 13 communication modules are needed, a second base
module must be connected through the sc1000 network.

Refer to Appendix A on page 141 for more information about the DIN rail expansion
modules.

26

3.6 Expansion cards

The sc1000 controller can be expanded with internal plug-in expansion cards. Each
expansion component can be identified with its serial number on the sc1000 network and
programmed as required. The serial number is located on the card.

It may be necessary to remove an existing expansion card, if the expansion card is
blocking access to certain connectors. Refer to section 3.6.6 on page 37 for more
information.

When an instrument is ordered, it comes pre-installed with the appropriate plug-in
expansion cards. The following options can be connected:

• Relay card with 4 relays

• Digital field-bus cards (Modbus (RS485), Modbus (RS232), Profibus DP)

• mA output card with 4 outputs

• mA input card with 4 inputs (analog or digital)

• sc-probe connectors

5.15 Formula editor for output and relay card

Formulas can be used as additional signal source for output and relay cards (DIN rail and
expansion cards). Each channel of the output or relay card can be used to run a formula.
The result of a formula can be used the same way like real measured values.

By using formulas, “virtual measurements” can be created (for example average values
from measured values of multiple probes). The virtual measured value is calculated from
the measured readings of other probes.

5.15.1 Add a formula

To add a formula:

1. Select SYSTEM SETUP,

a. for an output card continue with OUTPUT SETUP, mA OUTPUT INT/EXT,

OUTPUT 1-4, SELECT SOURCE, SET FORMULA.

b. for a relay card continue with RELAY, RELAY INT/EXT, RELAY 1-4, SENSOR,

5.15.3 Formula operations

Formulas can contain arithmetic and logical operations, numeric functions and
parenthesis to control the evaluation order.

Arithmetic operations like addition, subtraction, division or multiplication are based on
numeric calculations. Each channel of the relay or analog output card (internal or
external) can run the formula option. Arithmetical calculation results are preferred to drive
analog output channels.

Logical operations like AND,OR,NOR, XOR are binary based calculations, the result is
either true or false (0 or 1). Logical operations typically drive a relay, because relays
prefer to stay either ON or OFF which fits to the logic operation results.

Standard Operations

A set of functions is available to set the error and warning status of output modules. Each
of these functions requires a minimum of 2 (or 3) parameters and allows a maximum of
32 parameters. In calculations all functions take the value of first argument A as the
function result, so the use of these functions does not affect the calculated value.

6.3.1 Output setup menu

Note: This menu appears only if an output card is installed in the sc1000 controller.

The content of the output setup menu depends on the selected use/working mode:
Linear/Control or PID Control. The current output card can be used with the output
current linearly dependent to a process value or with the output current working as a PID
controller.

LINEAR CONTROL

In this working mode the output current is linearly dependent to a process value after it
has been processed by the internal formula parser (if prompted).

PID CONTROL

In this working mode the current output module generates a current output which tries to
control the process value. The PID controller controls the process value to be equal to
the set point when a disturbance changes the value of the process value or a new set
point is set.

The output current can be in a working range of 0

Note: The menus appear only if an input card is installed in the sc1000 controller.

The current input card can be used as an analog input card to measure an input current
in a range from 0
current input menu content depends on its use:

ANALOG CURRENT INPUT

The current input card connects devices with a current input interface to the sc1000
controller. Every current input channel can be configured separately, unit and parameter
are displayed in the measured value display. It is mandatory to have an corresponding
open jumper on the current input card to connect a device.

DIGITAL CURRENT INPUT

To differ two digital states the corresponding jumper on the internal current input card has
to be closed respectively the corresponding bridge has to be set at the external current
input card. The different states are recognized by closing or opening a contact between
the corresponding screwing terminals.

There is the possibility to adjust the input current measuring with an offset and a
correction factor to enhance the accuracy. By default these two parameters are set to “0”
(offset) and “1” (correction factor). When a channel is used as a digital input the display
will show the values “HIGH” or “LOW”.

Sets a hysteresis so the relay will not swing unregulated when the process value converges to

the set point.
PHASE is set to HIGH: The hysteresis is underneath the set point.
PHASE is set to LOW: The hysteresis is above the set point.

Default value: 0 minutes
Sets a maximum period of time. During this period the relay is turned on when passing the set

point. As soon as the time expires the relay is turned off regardless of the process value.
0=OnMax Timer is not active.

Default value: 5 seconds
Sets a delay time for the relay to turn on.

Default value: 5 seconds
Sets a delay time for the relay to turn off.
