OLCT 200 User Manual | 47
Latching set to YES causes the alarm to remain active even after the condition is gone
and only reset when the UP / RESET key is pressed from a data display.
5.4.1 Relay Configuration (if equipped)
Relay Config has the submenu shown in Figure 5-7. The optional relay PCB must be
installed to access this menu or a “HARDWARE NOT PRESENT” message appears.

K1 / K2 Failsafe
set for YES means the relay de-energizes during alarm and energizes
with no alarm. This is useful for also signaling alarm when OLCT 200 power is lost.
K3 is a FAULT alarm and is always failsafe.
K2 Acknowledge
set for YES means the UP / RESET key (RESET key during either
data display) will set K2 to the normal state EVEN when an Alarm 2 condition exists.
This is useful for silencing an audible device, driven from K2, during the alarm
condition.
K2 Refresh
set for ON causes an acknowledged Alarm 2 condition to reactivate K2 if it
continues beyond the designated Refresh interval (0-99 minutes). This feature insures
against “forgotten” alarms after an Acknowledge.
5.5 Sensor Information
Sensor Information has the SENSOR SETUP/INFO menus shown in Figure 5-8
