Current State of Relay ON/OFF, Auto/Manual<br />
The second parameter of the RELAYS function allows the user to determine<br />
whether the relay is ON or OFF <strong>and</strong> in automatic or manual mode<br />
shown in Figure 3-45. If in automatic mode, the relay is programmed to<br />
activate (ON/OFF) based upon a programmed function as listed.<br />
NOTE: Relay activation is controlled in the CONTROL function if in<br />
manual mode.<br />
Automatic control is used to turn the setpoint relay ON or OFF based upon<br />
user specified programming. The user cannot manually turn the setpoint<br />
relay ON or OFF when in automatic control. Manual control is typically<br />
used during system diagnosis when manual activation of a setpoint relay is<br />
required.<br />

Current Program for Automatic Control<br />
The third parameter of the RELAYS function displays the current user<br />
defined program which was selected for automatic control of the setpoint<br />
relays. The message shown in Figure 3-46 for example, means that the<br />
relay is activated based upon the cryopump motor being turned ON or OFF.<br />
