3.2 Wiring Safety Information

When making any wiring connections to the sc100 Controller, the following warnings and must be adhered to, as well as, any warnings and notes found throughout the individual installation sections. For more safety information refer to Safety Information on page 5.

DANGER Always disconnect power to the instrument when any making electrical connections.

3.2.1 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.

3.3 Electrical Installation

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.

3.3.3 Wiring for Power at the Controller

DANGER Explosion hazard. Do not connect or disconnect electrical components or circuits to the equipment unless power has been switched off or the area is known to be non-hazardous.

DANGER Do not connect AC power to a sc100 24 V DC powered model.

The sc100 can be purchased as either an 100–230 V AC powered model or a 24 V DC powered model. Follow the appropriate wiring instructions per the purchased model.

Important Note: A protective earth (PE) ground connection is required by the sc100 for both 100–230 V AC and 24 V DC wiring applications. Failure to connect a good PE ground connection can result in shock hazards and poor performance due to electromagnetic interferences. ALWAYS connect a good PE ground to the sc100 terminal.

The controller can be wired for line power by hard-wiring in conduit or wiring to a power cord. Regardless of the wire used, the connections are made at the same terminals. A local disconnect designed to meet local electrical code is required and must be identified for all types of installation. See Figure 13 and Figure 14 on page 16 for suggested local disconnect configurations.

1. Obtain appropriate fittings with NEMA 4X/IP66 environmental rating.

2. Loosen the screws using a phillips-head screwdriver and open the hinged controller cover.

3. Remove the high-voltage barrier (see Figure 9 on page 13).

4. Insert the wires through the strain relief fitting or conduit hub located in the right-rear access

hole in the bottom of the enclosure. Tighten the strain relief if used, to secure the cord.

5. Properly prepare each wire (Figure 11) and insert each wire into the terminal according to

Table 2 or Table 3. Tug gently after each insertion to ensure the connection is secure.

6. Seal any unused openings in the controller box with conduit opening sealing plugs.

7. Reinstall the high-voltage barrier and latch to secure.

Figure 11 Proper Wire Preparation and Insertion

1. Strip ¼-inch of insulation. 2. Seat insulation against connector with no bare wire exposed.

3.6 Wiring the Digital Gateway

The digital gateway is designed to provide a digital interface to the sc100 controller (or other appropriate digital controller). The non-sensor end is connected to the controller as described in

section 3.5.1 on page 19 for non-hazardous locations.

3.7 Connecting the Optional Digital Output

DANGER Explosion hazard. Do not connect or disconnect electrical components or circuits to the equipment unless power has been switched off or the area is known to be non-hazardous.

At this time, the manufacturer supports Modbus RS485, Modbus RS232, and Profibus DP communication protocols. The optional digital output card is installed in the location indicated in

Figure 21 on page 23. Terminal block J1 provides user connection to the optional network card.

The terminal connection is based on the selected network card. Refer to the instructions supplied with the network card for more details.

Note: The sc100/1720E system also supports the AquaTrend Network.

Surge Protection Recommendation for Profibus DP

Many industrial environments are vulnerable to power transients and lightning. Water and wastewater plants are notorious lightning targets. Lightning has become a leading cause of instrument failure at these facilities. Surge protectors limit the magnitude of over-voltage transients and protect equipment from damage. To be effective on Data lines, at a minimum, a surge protector should provide two stages of protection with sub-nanosecond response time. Data line surge protection should be installed on a Profibus DP network where it might be susceptible to lightning or transients. The purpose of the surge protector is to protect the device (instrument) it is located next to, not the network cable.

For the best performance/protection connect the surge protector as close as possible to the device to be protected and connect the device (instrument) ground connection through the surge protector’s ground to the local protective earth ground. Contact your local Profibus network component supplier for their recommendation as to which surge protectors may be best for your system.

Section 7 Warranty, liability and complaints

HACH LANGE GmbH warrants that the product supplied is free of material and manufacturing defects and undertakes the obligation to repair or replace any defective parts at zero cost.

The warranty period for instruments is 24 months. If a service contract is taken out within 6 months of purchase, the warranty period is extended to 60 months.

With the exclusion of the further claims, the supplier is liable for defects including the lack of assured properties as follows: all those parts that can be demonstrated to have become unusable or that can only be used with significant limitations due to a situation present prior to the transfer of risk, in particular due to incorrect design, poor materials or inadequate finish will be improved or replaced, at the supplier's discretion. The identification of such defects must be notified to the supplier in writing without delay, however at the latest 7 days after the identification of the fault. If the customer fails to notify the supplier, the product is considered approved despite the defect. Further liability for any direct or indirect damages is not accepted.

If instrument-specific maintenance and servicing work defined by the supplier is to be performed within the warranty period by the customer (maintenance) or by the supplier (servicing) and these requirements are not met, claims for damages due to the failure to comply with the requirements are rendered void.

Any further claims, in particular claims for consequential damages cannot be made.

Consumables and damage caused by improper handling, poor installation or incorrect use are excluded from this clause.

HACH LANGE GmbH process instruments are of proven reliability in many applications and are therefore often used in automatic control loops to provide the most economical possible operation of the related process.

To avoid or limit consequential damage, it is therefore recommended to design the control loop such that a malfunction in an instrument results in an automatic change over to the backup control system; this is the safest operating state for the environment and the process.

Appendix A Modbus Protocol

A.1 Modbus Troubleshooting

Table 8: Troubleshooting

Problem Possible Causes Solution

Verify sc100 settings match the Modbus master settings.Verify Modbus master Parity setting is set to None.

Check all network devices for termination or biasing settings. Only the ends of the network should have termination turned on and only one point on the network should be providing biasing.

Verify all addresses are unique and between 1 and 247.

Verify the requested register(s) Data Type matches the Modbus Master Request e.g. do not access a Slave Float value with a 2 byte Integer request. When requesting a Float (2 registers/4 bytes), both registers must be requested at the same time.

No Modus Response

Modbus Exception Response

Baud rate, or stop bits does not match settings of Modbus master

Bad RS232 or RS485 cable Replace/Repair cable

No or improper network biasing and termination.

Slave Address incorrect or duplicate address of another bus device.

Data Type incorrect
