For Tc 4; Calculation Example For T P - Honeywell TC Series Technical Information

Function
3 .2 .6 Test period t

for TC 4

P
The sensitivity of the tightness control TC can be ad-
justed by adapting the test period t
system. The longer the test period t
sensitivity of the TC. The longer the test period, the
smaller the leakage rate at which a safety shut-down/
fault lock-out is triggered.
The test period is set using the second jumper (on the
right in the picture).
The test period t can be adjusted in intervals:
P
TC 410-1: 10 s to max. 60 s,
10 s = factory setting,
60 s = without jumper.
TC 410-10: 100 s to max. 600 s,
100 s = factory setting,
600 s = without jumper.
