The instrument may go into alarm briefly, but the sensors stabilize quickly. If the instrument persists in alarm, acknowledge the alarm by pressing the switch. If alarm persists longer than 30 minutes, call ENMET AUDIO DEFEAT ALARM ACKNOWLEDGE customer service personnel. -
Page 10: Relay Contacts
ISA-300RAL ENMET 3.4.1 Relay Contacts Relay contacts are available for each alarm; these are SPDT, rated at 10Amp at 110V , and may be latching or non-latching as required by the application. They are accessed on the terminals next to each relay see Figure 2 & 2A. The contact positions are noted on the circuit board next to each terminal. -

Page 12: Operation
4.1 Normal Operation Condition With the ISA-300RAL installed as described in section 3, and in clean air, the POWER green LED is on, the display is lit and the information on the display is as shown in Figure 4 Display, for the sensor(s) installed in the ISA-300RAL. The red alarm and fault LEDs are not lit. -
Page 13: Alarm Latching
Differential Setting The Alarm 1 differential value is the delay of the ISA-300RAL staying in alarm condition until after the measured reading has returned past the alarm point by the differential value. Example: If the alarm point is Λ 10 and the differential is 2, the ISA-300RAL will go into alarm at 10 and stay in alarm until the reading has dropped below 8. -

Page 18: Low Cal/Zero Cal Adjust
5.3.1A Low Cal/Zero Cal Adjust A Low-Cal function should be performed only when the ISA-300RAL sensor are exposed to clean uncontaminated air. Use a cylinder of 20.9% oxygen to provide a clean air reference if necessary. Attach the cylinder to the calibration adapter, attach the adapter to the instrument and allow gas to flow over the sensor for up to 4 minutes. -
