2.4.3 Wiring the XDP alarms - J3
Terminal block J3 contains connections for the four XDP
alarms. To wire these alarms, complete the following steps:
NOTE: The following instructions show the wiring for fail-safe
operation. For non-fail-safe operation reprogram the alarm
or move the pin #1 connection to pin #3 for that alarm.
1. Connect the XDP high alarm (alarm 1) as follows:
a. Connect pin #1 (NC) to the alarm device input.
b. Connect pin #2 (C) to the alarm device return.
2. Pin #3 (NO) is not used for fail-safe operation
3. Connect the XDP high high alarm (alarm 2) as follows:
a. Connect pin #4 (NC) to the alarm device input.
b. Connect pin #5 (C) to the alarm device return.
c. Pin #6 (NO) is not used for fail-safe operation
4. Connect the XDP low alarm (alarm 3) as follows:
a. Connect pin #7 (NC) to the alarm device input.
b. Connect pin #8 (C) to the alarm device return.
c. Pin #9 (NO) is not used for fail-safe operation.
5. Connect the XDP low low alarm (alarm 4) as follows:
a. Connect pin #10 (NC) to the alarm device input.
b. Connect pin #11 (C) to the alarm device return.
c. Pin #12 (NO) is not used for fail-safe operation.
2.4.4 Wiring the calibration relays - J7
Terminal block J7 contains connections for the four
calibration relays. To wire these relays, complete the
following steps:
NOTE: These relays are configured for non-fail-safe
operation.
1. Connect the process/cal relay (relay 1) as follows:
a. Pin #1 (NC) is not used for non-fail-safe operation.
b. Connect pin #2 (C) to the alarm device return.
c. Connect pin #3 (NO) to the alarm device input.
2. Connect the zero/span cal relay (relay 2) as follows:
a. Pin #4 (NC) is not used for non-fail-safe operation.
b. Connect pin #5 (C) to the alarm device return.
c. Connect pin #6 (NO) to the alarm device input.
3. Connect the AutoCal indication alarm (relay 3) as follows:
a. Pin #7 (NC) is not used for non-fail-safe operation.
b. Connect pin #8 (C) to the alarm device return.
c. Connect pin #9 (NO) to the alarm device input.
4. Connect the Auto verification alarm (relay 4) as follows:
a. Pin #10 (NC) is not used for non-fail-safe operation.
b. Connect pin #11 (C) to the alarm device return.
c. Connect pin #12 (NO) to the alarm device input.
2.4.5 Wiring the system analog output - J5
Terminal block J5 contains connections for the system
analog output. To wire the system analog output, complete
the following steps:
1. Connect pin #1 to positive input on the device.
2. Connect pin #2 to the return line from the device.
3. Pin #3 has no connection.
2.4.6 Wiring the XDP analog output - J8
Terminal block J8 contains connections for the XDP analog
output. To wire the XDP analog output, complete the
following steps:
1. Connect pin #1 to positive input on the device.
2. Connect pin #2 to the return line from device.
3. Pin #3 has no connection.
2.4.7 Wiring the serial port - J4
Terminal block J4 contains connections for the RS-232/RS-
485 (RS-485 supports multi-drop installations) serial port. To
wire the serial port, complete the following steps:
1. Connect pin #1 to the transmit pin on the PC serial port.
2. Connect pin #2 to the receive pin on the PC serial port.
3. Connect pin #3 to the return pin on the PC serial port.
NOTE: This connection may be made with a Panametrics
#704-668 cable. If this cable is used, connect the red wire to
pin #1, the white wire to pin #2, and the green wire to pin #3.
