Panel Mounting

• E-680 controller should be installed inside a suitable grounded metal enclosure (panel). This must prevent the live parts being accessible to human hands and metal tools.
• E-680 controller does not include a power switch. Therefore, the power supply of the controller and power outputs must be wired through the proper fuse or circuit breaker.
• To minimize the pick-up of electrical noise, the wiring of low voltage lines, particularly the sensor inputs should be routed away from the high-current power cables. If this is not possible use screened cables and apply grounding.
• The cables used for powering the controller and the power outputs must conform to the standarts IEC 60245 and IEC 60227.
• Cut a hole in the panel. (See the figure for overall dimensions.)
• Slide the controller into the cutout from the front of the panel.
• There are three clamp holes located at the top and the bottom side of the device. Use the convenient ones and fit the mounting clamps to the controller ensuring the lugs are located in their slots.
• Fasten the mounting clamps using the retaining screws.

Program led lights when entered to the configuration mode, and Manual led lights during Manual mode, Set 1 led lights during SET 1 common alarm and Set 2 led lights during SET 2 common alarm period. During normal mode, channel numbers are displayed in the first two digits, measured values in the digits 4-7 and alarm information in the last digit of the 9 digit LED display. Channel information can be watched automatically or manually. In automatic mode, channel information can be monitored consecutively. The display time of a channel data is equal to GA parameter in seconds. button is used for switching from automatic to manual or manual to automatic mode. In manual mode only one channel can be monitored, channel number is selected by and buttons.

When the device is in normal operation state, the button can be used to switch to the totalizer and the alarm pages. When the device is in manual mode and the button is pressed, totalizer value is displayed. In this page, simultaneously pressing and buttons reset totalizer. Next to the totalizer page, alarm pages are reached. All alarms (Set 1, Set 2) can be seen together in these pages. In the first alarm page, alarms of channels 1 to 16 are displayed and letter A is shown in the last digit. In the second alarm page, alarms of channels 17 to 32 are displayed and letter B is shown in the last digit. In the third alarm page, status of the output relays R1 to R16 are displayed and letter O is shown in the last digit. Figure 2.2. shows the display format of the alarm pages. While in the totalizer or alarm pages pressing the button reverts to the normal operation page. Alarm status of the channel that are not active or closed for scanning are shown as empty.

Configuration Pages

General Configuration Page

Alarm Configuration Page

The alarm types and the principle of generating alarms are given in the figure on the right. Alarm parameters are RP, CT1, CT2, PLNG, A1SP, A1HY, A1TP, A1RL, A2SP, A2HY, A2TP and A2RL.For each channel, set points A1SP and A2SP are defined. Those can be directed to common and independent alarm relays according to the values selected for A1TP and A2TP. When A1TP and A2TP is selected as OFF, the alarms will not be activated. When alarm type is choosen as LO1 or HI1 related alarm can only be directed to common alarm relays. Those relays are RO1 for Set 1 and RO2 for Set 2. When alarm type is selected as LO2 or HI2, alarm can only be directed to independent relays determined by A1RL and A2RL parameters.

Independent relays are R1, R2,…,R16. When alarm type is selected as LO12 or HI12, related alarm is directed to the common and independent alarm relay described as above. Different alarms can be forwarded to the same independent relay. In this case related relay is used commonly by those alarms. RP is valid for all defined alarms, and defines the number of scans for alarm condition. As an example, if RP is selected as 3, alarm will be triggered, if the alarm condition persists at least three scan period. CT1 and CT2 are only valid for common alarms and at alarm conditions it defines whether the relay is energized continuously or during the defined pulse length. CT1 determines control type of RO1, and CT2 determines control type of RO2 relay.
Note: When any alarm condition occurs, the device switches to manual mode and indicates the channel information which causes the alarm state.

Input Configuration Page

The SCAN parameter of unused channels should be adjusted as OFF. This reduces the overall channell scan time. If the input type is changed, jumpers on the input multiplexer card must also be organised accordingly. (See Section 2.5 E-680 Jumper Settings) Otherwise reading will be false. Incase of any constant measuring error, this error can be removed by giving suitable value to INS parameter.
Example: If the sensor produces 3°C more than normal value, error may be removedby adjusting INS parameter to -3.
Note: When input type is selected as CUST, it will be operate as PT if there is no custom inquiry.

Table 2.2.

When the linearization type selected as FCMP or CMP, related channel can be used for flow rate measurement. Flow rate measurement is calculated using differential pressure principle based on orifice plates with pressure and temperature compensation. In related channel input configuration, K1, C1, K2, C2 parameters determine the pressure channel, design pressure, temperature channel and design temperature respectively. When the INPT parameter is set to AVG, related channel will be a virtual channel and input value belonging to this channel is calculated as below. Input Value = (PV ×C1+PV ×C2+PV ×C3+PV ×C4)/100.0 K1 K2 K3 K4 (PV: Process Value of X. channel, CX: Coefficient of X. channel) KX This input is linearized according to LINZ parameter like other inputs to see the input value as process value LINZ parameter must be set as LIN.
When the channel is on display, pressing and together make the sum zero.
The channels of which the channel numbers are greater than input numbers are virtual. In these channels input type can only be chosen AVG. Otherwise, no calculation can be done.

Security Configuration Page

Calibration Page
The basic calibration of the controller is highly stable and set in the factory. Any erroneous operation in the CALB page will corrupt the calibration parameter, and measurements will be faulty. The calibration parameters of the controller can be reinstalled in the CALB page. If accurate calibration devices are not avaible, entering to the CALB page is not advised.

Warning Messages
During normal operation, channel numbers are displayed in first two digits of the display, the measured value in digits 4-7 and alarm information in digit 9. If there is any fault at the input information, measured value can not be seen. Instead of it, the messages at the following table are displayed.

Connection Diagram

Back panel view of E-680 device is shown in Figure 2.3.. There are 3 connection blocks X, Y and Z are located on the back panel. Connection group X is used for the processor and the power supply card. Connection group Y is used for multiplexer or relay card. Depending upon the configuration, this block may be used or not. Connection block Z is used only for multiplexer card. The connections of processor and the power supply card is given in Figure 2.4., the connections of relay card that can be used in group Y is given in Figure 2.5. various connections of the multiplexer card that can be used in group Y and Z are given in Figure 2.6., Figure 2.7., Figure 2.8. and Figure 2.9.. The number of terminals on the multiplexer and relay card depends on the type coding. (See Section 1.1. Type Coding)

Jumper Settings

The jumper settings are different for TC (mV / V), RT, mA and 10 V inputs. The input signal applied to any channel must be compatible with INPT parameter of ICNF Input Configuration Page and jumpers on the input multiplexer card. Device has 1 or 2 multiplexer card according to the number of channels. Devices, having channel number up to 16 have a single, devices having more than 16 channels have 2 multiplexer cards. The jumpers are located on the multiplexer cards. Figure 2.10. shows top view of multiplexer card. In order to access to multiplexer cards, dismantle two screws at the back side and remove the cover. Upper connection group Z is the first multiplexer card. It includes the channels 1-16. If device has more than 16 channels, channel 17 to 32 are on the multiplexer card located at the middle slot. In order to reach this card, unscrew the upper two screws and slack the lower two screws and turn the fixing plate. Then remove the cable of first multiplexer card and dismantle it by pulling from rails. After completing necessary arragments, first multiplexer card is attached by the same way to its place. Screw the plate to fix the cards again. Finally place the cover. Multiplexer card address jumpers must not be changed.

Communication Connection

Typical communication network for E-680 device is given in Figure 2.11. More than one E-680 device can be connected to the same line and all information from devices can be collected in one center (PC, PLC). RS- 485 is used for communication. When a PC is used as a master, E-IB-10 (RS-232 / RS 485 inverter) should be used. This because of standard PC’s do not have RS-485 connection. Communication protocol is Modbus. According to this protocol, each device connected to line must have a different address. Communication address of E-680 devices are set by ADRS parameter in GCNF page.
