Alarm Relays
Part 17997 Rev. 6, March 2011 10-5
the H201Ci triggers a fail alarm, regardless of the H201Ti’s fail alarm relay). As far as the
fail alarm relay, the coil is energized in normal operation (no alarm).
Table 9-1 on page 9-3 lists the possible states of all relays. The state of each relay can be
determined as follows:
• H201T i :
– By displaying RelayH State , RelayHH State and SysOk State in the Relays/Analog
submenu.
– By looking at the LED’s on the right side of the I/O module (see Figure 2-7 on
page 2-12).
– By verifying the state of the alarm contacts on the Alarm Contacts 9-Terminal Block
(item 12 in Figure 2-5 on page 2-9).
• H201C i -1:
– By looking at the LED’s on the circuit board (see items 13 to 18 in Figure 3-7 on
page 3-12).
– By verifying the status of the alarm contacts on the terminals 7 to 15 of the Main
Terminal Block (item 6 in Figure 3-6 on page 3-11).
– By looking at the illuminated 1 (High alarm) and 2 (High-High alarm) push-buttons
on the enclosure door.
• H201C i -C: No alarms.
Table 10-2 on page 10-5 lists the possible states of the alarm contacts.

10.2.3 Operation Modes of Alarm Relays
The mode of each alarm relay is set using the corresponding RelayMode parameter in the

four operation modes:
• Normal : See Section 10.2.3.1 on page 10-6.
