module via the Control Register (see Appendix B). If interrupts are enabled,

the system generates an interrupt after writing to any relay control register.

to indicate the end of relay closure/settling time.

As shown in Figure 1-5, the Interrupt Request Level switch selects the

priority level that will be asserted. The Interrupt Request Level switch is set

in position 1 as shipped from the factory. For most applications this priority

level should not be changed. The interrupts are disabled when set to

position 'X'. To change the setting, set the switch to the level required.

NOTE Interrupts can also be disabled using the Control Register (see Appendix

B). Also, consult your mainframe manual to make sure backplane

jumpers/switches are configured correctly.
