b.Calibration Handshake/Logic I/O. The output can either be an alarm or provide the handshaking to interface with an IMPS 4000 or SPS 4001B. For more information, refer to "Logic I/O" in Section 4: Configuration of Oxymitter 4000 with LOI, and either the IMPS 4000 Intelligent Multiprobe Test Gas Sequencer Instruction Manual or the SPS 4001B Single Probe Autocalibration Sequencer Instruction Manual.

c.If autocalibration is not utilized, a common bi-directional logic contact is provided for any of the diagnostic alarms listed in Table 8-1.The assignment of alarms which can actuate this contact can be modified to one of seven additional groupings listed in Table 4-1.

The logic contact is self-powered, +5 VDC, 340 ohm series resistance. An interposing relay will be required if this contact is to be utilized to annunciate a higher voltage device, such as a light or horn, and may also be required for certain DCS input cards. A Potter & Brumfield R10S-E1Y1-J1.0K 3.2 mA DC or an equal interposing relay will be mounted where the contact wires terminate in the control/relay room.

4.Install cover (27, Figure 9-4).
