PG-2000 Toxic Gas Monitor For Ventilation Control Flexible monitoring and control for ventilation of toxic gas in parking garages, warehouses and maintenance facilities The PG-2000 offers an intelligent solution to gas monitoring and ventilation control. More than 30 years of gas detection experience has contributed to this highly functional monitor.
PG-2000 The PG-2000 control panel offers a keypad and LCD user interface for easy set-up and operation. The Arjay microprocessor scans the field of sensors and groups them into building zones for fan control. EC-Gold sensors are used in the field for reliable and accurate monitoring of the target gas. The carbon monoxide sensors have the unique capability to generate a gas test daily to verify the sensor response.

pg2000capum45.DOC Model: PG-2000 1.3 Rev: 4.5 SPECIFICATIONS OPERATION The CAP can access a maximum of 80 EC Gold transmitters assigned to up to 8 zones and set Sensor Fault, High-High, High, and Low alarms based on ppm values read from the transmitters. In addition, the maximum and average ppm values are reflected on two optional 4-20mA outputs per zone. USER INTERFACE Calibration and setup 4 Line x 20 char LCD and 4X4 membrane keypad. Network RS-485 Modbus protocol connection to EC Gold sensors.

Model: PG-2000 3.3 pg2000capum45.DOC Rev: 4.5 DISPLAY SCREENS After powerup, and the initial startup screen has been displayed for about 3 seconds, the CAP scans all active EC Gold transmitters on the network (as set by the "number of remotes" setting explained later. This may take several seconds depending on the number. The following screen will now appear: 3.3.1 ZONE ALARM STATUS SCREEN The following is a typical display: z1: Low Alarm z2: ok z3: ok z4: ok The above display is for example only.
Model: PG-2000 pg2000capum45.DOC Rev: 4.5 The bottom line displays the common alarm status. Based on the current alarm state, “OK”, “Low Alarm”, “High Alarm”, or “High High Alarm” is displayed. The status reflects the alarm condition including user settable time delays. 3.3.3 AUXILIARY MODULE STATUS SCREEN To view this screen, press the DISP key from the Overall Alarm Status Screen. Aux1:ok Relays 1-8: 10000000 Aux2:ok Relays 1-8: 00000001 The above display is for example only.
Model: PG-2000 pg2000capum45.DOC Rev: 4.5 Each zone may have 2 mA modules: one for the max ppm in the zone and the other for the average ppm value. If a mA module is not installed, then N/A is displayed. If it is responding on the network then “Ok” is displayed. If it is not responding then “N/R” is displayed. 3.3.
Model: PG-2000 3.6 pg2000capum45.DOC Rev: 4.5 SET ALARM VALUES, DELAYS AND RELAY MAP 1. Press the CONT key then press 1 for Gas Alarms / mA Span. If coming from the normal display screens, enter the password at the prompt. The default factory set password is 2000. 2. Select a number (1-4) to select a gas with which to associate alarm thresholds. For example in a system with CO and NO2 EC Gold transmitters, Gas#1 is set for CO and Gas#2 for NO2. Gases #3 and 4 are set to Unused 9 (code 23). 3.
Model: PG-2000 pg2000capum45.DOC Rev: 4.5 4. After selecting the desired gas by pressing 1 in step above, enter the high and low thresholds for the Low Alarm. The gas concentration must rise above the high threshold to set the Low Alarm, and must fall below the low threshold to clear the Low Alarm. 5. After setting the Low Alarm thresholds, the system automatically prompts for the High and High-High alarms thresholds. 6. Enter the full-scale value in ppm of CO for the 4-20mA output.
Model: PG-2000 4.0 pg2000capum45.DOC Rev: 4.5 MISCELANEOUS SETUP Each remote EC Gold transmitter may be individually setup and calibrated via the CAP unit. Setup from the CAP is more convenient than using the EC Gold integral switches. Calibration, on the other hand, is usually best done at each EC Gold since the sensor has to be gassed. A handheld calibrator may be purchased for easy calibration. NOTE: The CAP acts as a user interface to the remote EC Gold transmitter being calibrated.
Model: PG-2000 pg2000capum45.DOC Rev: 4.5 3. At the prompt, enter the address number of the desired EC Gold transmitter to be calibrated. 4. From the Calibration menu press 1 for Autocal. 5. Gas the EC Gold sensor being calibrated with the first gas. Ambient air can be used as 0 ppm ONLY if it is certain that there is no CO in the air. Enter the concentration of the first gas in ppm for this first point.
pg2000capum45.DOC Model: PG-2000 5.0 Rev: 4.5 BMCS ACCESS The Enmet CAP's (Central Access Panels or Scanners) may be accessed via an RS-485 link using the Modbus protocol. Up to 28 CAP units may be connected on a single network – in this case only 2 are connected. The BMCS acts as a Modbus master. 5.1 SETUP Each CAP unit must be given a unique Address so it can be specifically be accessed by the BMCS. This is done as follows: 5.2 • Press the Setup key on the CAP keypad.
