I. SPECIFICATIONS Model: SEC 3100 Transmitter For use with: SEC Millenium and SEC Signature series infrared sensors and SEC 3000 Toxic and Oxygen gas sensors. Part Number: SEC 3100100 Output (analog): 4-20 mA (Source type), max. 1000 Ohm load at 24 VDC supply voltage Output (digital): RS485 LAN (isolated) Output (relays): Three (3) Alarm, Low, Mid High.
II GENERAL DESCRIPTION CONVENTIONS The following conventions are used in this manual. ! Warning Statement VDC (DC Voltage) SEC 3100 The SEC 3100 transmitter is designed to be used with the SEC Millenium, SEC Signature infrared gas sensors or SEC 3000 toxic gas detectors. The SEC 3100 is a microprocessor based intelligent transmitter continuously monitoring information from the gas sensor. The LCD of the SEC 3100 displays the gas concentration and sensor status.
rise. In addition, if the temperature of the gas is hotter than ambient air or mixed with gases that are lighter than air, it could also rise. • How rapidly will the gas diffuse into the ambient air? Select a location for the sensor that is close to the anticipated source of a gas leak. • Wind or ventilation characteristics of the immediate area must also be considered. Movement of air may cause gas to accumulate more heavily in one area than in another.
The 4 to 20 mA output of the SEC 3100 sensor is a non-isolated current source. Current Output and Corresponding Status Current Output 0-20 mA 0.0 mA 0.2 mA 0.4 mA 0.8 mA 1.0 mA 1.2 mA 1.6 mA 2.0 mA 2.2 mA 4.0 mA 5.6 mA 8.0 mA 12 mA 16 mA 20 mA 20.
IV. MAGNETIC SWITCH OPERATION The SEC 3100 has three (3) magnetic switch pickups on the Display PCB. The picture below shows the location of the magnetic switches labeled UP, DOWN and ENTER. Placing a magnet in close proximity to one of the switches will cause the following operations to occur.
V. MENU OPERATION Inital Power Up Sequence of the SEC 3100 SYSTEM BOOT PROCESS --- WAIT FOR SYNC –- SYSTEM BOOT PROCESS -WAIT FOR SENSOR - INITIALIZING WARM UP WARM UP 0 ID: xx SN: xxxxx TYP: x.x VER: x.x ID: xx 0-20.0PPM WF6 ENT TO ABORT ID: 1 0-20.0 PPM WF6 MC - REMOVED In normal operating mode. Actual gas concentration will be displayed to the left of ID #, Range, Gas Type, MC (Memory Card) status.
Selecting Enter when the SEC 3100 in in normal operating mode will advance to the following display: * EJECT MEMORY CARD INFO MAIN MENU Down Arrow Selecting Enter will allow the operator to safely remove the Memory Card. Arrow Down EJECT MEMORY CARD * INFO MAIN MENU Entering the INFO menu will display the following screen * UNIT INFO SENSOR INFO STATS EXIT Selecting Enter at UNIT INFO displays the following: 3100 UNIT INFO: SN- XXXXXXXXXXXXXXX VER- X X.XXX.XXX SN is the SEC 3100 serial number.
Main Menu and Sub Menus EJECT MEMORY CARD INFO * MAIN MENU Enter Calibration Menu Used to calibrate the gas sensor. * CALIBRATION ALARM RELAY Down Arrow Alarm Menu Used to set alarm level set points and parameters. CALIBRATION * ALARM RELAY Down Arrow Relay Menu For setting alarm relay On & Off delay & Energized states.
Calibration Menu * CALIBRATION ALARM RELAY Enter Using the Up and Down arrows allows the operator to move the cursor (*) to select a function. * ZERO SPAN CAL. VAL EXIT 0 To Zero the sensor apply clean air (N2 for an oxygen sensor) and select enter. The following will be displayed. CALIBRATION PROCESS ------- WAIT ---------- Then the following will be displayed. CALIBRATION PROCESS ------- DONE ---------- Once complete the following will be displayed. The sensor has been successfully zeroed.
To Span the sensor with calibration gas use the Up and Down arrows to select the following display. ZERO * SPAN CAL. VAL EXIT 3 Apply span gas to the sensor for the appropriate amount of time in order for the sensor to stabilize. The gas reading is displayed to the right of ZERO. Once stable select Enter. This will go the display: CALIBRATION PROCESS ------- DONE ---------- If calibration span gas is still present the display will read: GAS LEVEL : 5 CALIB.
Alarm Menu CALIBRATION * ALARM RELAY Enter * LOW MID HI EXIT Enter Select the Alarm Relay (LOW, MID, HI) using the down arrow. Once the cursor is on the alarm relay you wish to configure, hold the magnet over Enter. The example LOW will be used. The same operations can be used to set the MID or HI relays. * ALARM LOW 4 LATCH ACTIVE EXIT Selecting Enter will display the following screen allowing the alarm set point to be programmed. Using the Up and Down arrows will change the set point.
Arrow Down ALARM LOW LATCH * ACTIVE EXIT HI Selecting Enter will allow the operator to change the operation of the relay operation from Active HI to Active LOW. HI activates the relay on a rising alarm level. LOW actives the relay when the alarm threshold falls below the alarm set point. Once the correct operation is selected, use the Down arrow to advance to the next menu item. Arrow Down ALARM LOW LATCH ACTIVE * EXIT Selecting Exit will advance to the next menu.
Relay Menu CALIBRATION ALARM * RELAY Selecting Enter will advance to the following menu. * LOW MID HI Arrow down to the next screen will be * FAULT EXIT Select the Alarm Relay (LOW, MID, HI, FAULT) that is to be configured using the down arrow. Once the cursor is on the correct alarm relay, hold the magnet over Enter. The example LOW will be used. The same operations can be used to set the MID, HI, or FAULT relays.
Select Enter ON DLY LOW * OFF DLY ENERGIZED EXIT 0 Select Enter ON DLY LOW * OFF DLY EXIT 0 * Using the Up and Down arrows the operator can change the OFF delay time for the relay to turn OFF after the reading has decreased below the alarm point threshold. The time is measured in seconds (0-255). Once the correct time is displayed select Enter to accept the new value. Then Exit the menu and proceed on to the next selection.
Network Menu * NETWORK HIDE Select Enter * ZONE 0 ID ONLINE EXIT Select Enter to change the Zone number of the SEC 3100. * ZONE 0 ID ONLINE EXIT * Use the Up and Down Arrows change the Zone number (0-255). Once the correct Zone number is displayed select Enter. Arrow Down to ID. To change the ID number select Enter. Use the Up and Down Arrows to change the ID number (0-255). Once the correct ID number is displayed select Enter. ZONE * ID 1 ONLINE EXIT * Arrow Down to Online.
Hide Menu NETWORK * HIDE NO Using Enter the operator can toggle between Hide YES and Hide NO. The Hide function allows the operator to not display the gas reading until the Low Alarm threshold is exceeded. All outputs will function as normal when the Hide mode selected to YES. Self Test Menu * SELF TEST DATE TIME Selecting Enter for the Self Test will make the sensor generate a 4-20 mA input into the SEC 3100 from 4 mA to 20 mA (0-fullscale).
Time Date Menu SELF TEST * DATE TIME Entering this menu will allow the operator to set the time and date of the SEC 3100 real time clock. * DATE TIME EXIT 1 / 30 / 2006 Selecting Enter will locate a cursor (*) above the number allowing the operator to use the Up Down arrows to increase or decrease the numbers. Once the correct number is displayed, select Enter with the magnet and the cursor will advance to the next number. Date is MM/DD/YYYY. Time is HH/MM/SS. Below is an example.
Select Enter * EXIT Selecting Enter again will return the SEC 3100 to normal operation.
Diagnostics Menu * DIAGNOSTICS REST RELAYS EXIT The Diagnostics Menu will allow the operator to enter the Locator Mode and Toggle Relays on and off to verify operation. Selecting Enter will display the following: * LOCATOR OFF TOGGLE RELAYS EXIT The Locator function is normally generated by the SEC 3500 operator interface. It can be used at the SEC 3100 to function as a lamp test. Selecting Enter will turn the Locator on.
Reset Relays Menu DIAGNOSTICS * RESET RELAYS EXIT The Reset Reset relays Menu will allow the operator to reset latched relays. Latched relays will be indicated by a blue flashing Alarm LED. Select Enter and any latched relays will be reset.
