Scheme logic
Figure 2.8-2 shows the scheme logic for THM. THM has two thresholds; threshold “A” is used
for alarming, threshold “T” for tripping. The name of the output signal for the alarm is termed
THM-OPT-ALARM and that of the output signal for tripping is termed “THM-OPT-TRIP”.
The threshold level for the alarm is set using setting [
THM-Alarm
] as a percentage of the
tripping threshold. The alarm signal is disabled when
Off
is set for scheme switch [
THMA-EN
].
The trip signal is prevented when
Off
is set for scheme switch [
THMT-EN
]. PLC signals
THMA_BLOCK and THMT_BLOCK are used to block the operation of THM.
Figure 2.8-2 THM Logic
When wishing to have a test about pre-load current (Ip), the user should set a test value for
the setting [
THM-IP
] followed by setting [
THM-Test
]=
On
.
