OMD-2005
The unit is supplied with 2 works-adjusted alarms at 15 ppm. Other set points (10 ppm or 5 ppm) are possible and can be adjusted on site at any time by using the buttons at the front panel.
If an alarm set point is exceed, the alarms are visible at the front panel and the appropriate relays are switched. In case of malfunction the System LED at the front panel will change from blinking green to permanent red and the appropriate relay will switch the contacts.
For the data logging function the unit requires an status input from the separator and a feedback signal from the valve position limit switch. (See Fig. 1, Pos.6) Furthermore a 0(4) – 20 mA (equal to 0 – 30 ppm) signal output is available for driving a recorder or external meter.
