(part 2)

2. System 57 (5701, 5704) The System 57 is a fully programmable system
Card swapping is only recommended
with factory pre-configured Control Cards
using EIS software (Engineering Interface Software) for cloning the card to be replaced
Relay cards can be changed out without programming, as long as, the same style card is used

3. 5701 Input Modules & Link Settings
Each style of Transmitter has their own Link settings - (refer to the “5701 Control System” manual under Chap. 4 “Installation Instructions)
The Links are located on the 4-20mA Sensor Drive Module (4-20mA input)(Part # A-0283)
4-20mA input (violet Control Card face)
Direct Sensor Input Module is used only with Catalytic style sensors (mV input)(Part # A-0284)
Catalytic input (gray/blue Control Card face)

4. 5701 Input Modules & Link Settings (cont...)
4-20mA Input module unplugs by simply removing the control card from the rack and pulling straight and change the Links accordingly.
Re-installing CAUTION: The modules are NOT keyed. Be sure to re-install pin1 to pin 1.

5. 5701 Input Modules & Link Settings (cont...)
Catalytic Input Module has no jumper settings.
Re-installing CAUTION: The modules are NOT keyed. Be sure to re-install pin1 to pin 1.

6. 5701 Relay Card Types and Connections
There are 4 types of relay cards available
Field Interface
No relay contacts
Double SPCO
3 relays contacts
Triple SPCO
5 relay contacts
Triple DPCO
8 relay contacts
These relay contacts are software fixed for event

8. 5701 Relay Card Types and Connections (cont...)

9. 5701 Sensor/Transmitter Connections
Note: Follow the installation instructions for the appropriate Link settings

10. 5704 Control Cards
Unlike the 5701 cards, the 5704 cards cannot be re-configured for the different input types
4 channel cards
Catalytic input (gray/blue face)
4-20mA input (violet face)

11. 5704 Relay Card Types and Connections
There are 2 types of relay cards available
Quad Relay Card
4 programmable SPCO relays
Quad Relay with Expansion Card
16 programmable relays
12 SPCO contacts
4 SPST contacts
2 slots in rack required
NOTE: Do Not use the default relay assignments. These relays are shipped in different configurations, including the factory default compared to the manual.

and Connections (cont...)

14. 5704 Sensor/Transmitter Connections
Note: Follow the installation instructions.
Note: This connection must be made
as shown. Including the “0V” connection from
the power supply to any one of the “NS”
terminals.

15. Power Connections NOTE: Always calculate power draw of
Transmitters and Control Cards when staging or expanding systems
(see page 4-8 of 5704 manual or page 4-10 of the 5701 manual).
(Page numbers may vary depending manual revision)

16. 4-20mA Output
5701
Each card has the option of having a 4-20mA output
There is only 1 type available
The wiring dictates Sink/Source configuration
When using this option always refer to the manual for the appropriate configuration
Software programming is required to instruct the card of the feature
5704
Each channel on the card has the option of having a 4-20mA output
There are 2 types available
Current Source
Current Sink
When using this option always refer to the manual for the appropriate configuration
Software programming is required to instruct the card of the feature

17. Troubleshooting Control Card Fault Codes The Fault codes run from
74 through 99
(Consult manual for meanings
& corrective actions)

18. Troubleshooting (cont…)
Engineering Card Fault Codes
As the Engineering card only has LED’s
The faults reported are by flashing them accordingly
(Consult manual for meanings & corrective actions)

19. Troubleshooting (cont…)
4-20mA Input card
Insert Engineering Key
Select card (5704 select channel)
Press the “Signal” key on the Engineering card
The control card will display
This reading is the live 4-20mA’s being received at the card
If the reading is “0.0mA”, then remove the “01” line and measure between
Source configuration - “01” and “NS”
Sink configuration - “01” and “S”

20. Troubleshooting (cont…)
Catalytic Input card
Insert Engineering Key
Select card (5704 select channel)
Press the “Signal” key on the Engineering card
The control card will display
This reading will be around zero and will very from point to point, under a no gas condition
If the reading is displaying +/-999.9, then remove the sensor and perform a resistive check (705 series)
Blue to White = approximately 3.5 ohms
Brown to White = approximately 3.5 ohms
These two readings must match

21. Calibration Insert Engineering Key Select card
Push the “Zero” button on the Engineering card
The card will automatically “Inhibit” itself
Apply Zero
Wait for display to stabilize (indicating “ ”)
Press the Check mark “ ”
Press the “Span” key
The display will show “50”, this is the concentration to be applied
Use the up ( ) and/or down ( ) arrows to select the concentration being applied

22. Calibration (cont...) Apply gas to sensor
Wait for display to stabilize (indicating “ ”) and add 45 seconds
Press “ “
Remove gas and wait 1 minute (or until readings on display drops to zero)
Press “Inhibit” button
The card has now been calibrated and back in operation
Note: When possible using a forced mA output (Digi-series transmitter) is preferred.

23. Calibration (cont...)
Calibration for NEW catalytic sensors only (Direct sensor input only)
Perform the steps previously mentioned except:
Instead of using the “Span” button you will now use the “1st Span” button
This sets a flag enabling the control card to monitor the degradation of the sensor between calibration

24. Alarm Set Points Using the Engineering card
Insert Engineering key
Select card
Select channel (5704 only)
Press “Alarm” button until A1 appears
use Up and down arrows to achieve alarm trip point
Press the “ ” (note: this will set the value and exit)
Press “Alarm” button until A2 appears
(continue using steps 5 and 7 for the remaining settings)
There are 2 ways of setting alarm points
Using the EIS software
Using the Engineering card
Using the EIS software (to be discussed later)

25. Alarm Set Points (cont…)
Caution: After you complete the previous steps (after pressing “Alarm” button 6 times) you will see “TEST” appear on the display
If you choose to skip this, then simply remove the Engineering Key
If you choose to test the alarms (setting off the alarms), then:
Press the “Inhibit” button
Use the Up and Down arrows for the different levels
When completed remove Engineering key and re-install
Press “Inhibit” button
Remove Engineering key and you are back online
