Board configuration
Table 11 is a brief description of each configurable point on the XRC
diagram shows the location of these items (Figure 43).
Jumper No. Description
RS-485 Termination: When there are multiple XRC
J7 and J10 must be properly terminated. When the XRC
1 and 2. If the unit is first or intermediate, the jumper should be across pins 2 and 3.
Pulse Input (PI) Debounce: When using any of the digital inputs as pulse inputs you may want to enable
J5, J9, J11 and debounce for that input. Debounce enables an RC Time Constant that will tend to debounce noisy relay or switch
J12 closures. However, if the PI is monitoring a fairly high-speed input, enabling debounce could cause a loss of some
of the pulses. To enable debounce jumper across pins 2 and 3.
Analog Input (AI) Configuration: The XRC
J21, J22, J24,
A jumper across pins 2 and 3 establishes the associated AI as a 0-10 Vdc voltage input. A jumper across pins 1
J25 and J26
and 2 establishes the associated AI as a 0-20 mA Current Loop Input.
Lithium Battery Backup: J1 enables or disables memory backup via the lithium cell battery. A jumper across pins
1 and 2 enables RAM memory backup. If the jumper is removed (or across pins 2 and 3) the lithium cell is not
J1
enabled for memory backup. Should power be lost or disconnected while the lithium cell is not enabled, the
G4
XRC main processor board will execute a COLD Boot and all historical data will be lost.
Security Switch: If the security switch is on and a local connection is made to the unit via PCCU, the proper
security code must be entered. If the proper security code is not setup in PCCU, the operator will be unable to
