TC
Tightness control for checking two safety valves be-
fore and after burner run, with adjustable measure-
ment time for adjustment to different test volumes,
leakage rates and inlet pressures. The TC is used in
industrial thermoprocessing equipment, on boilers
and on forced draught burners.
TC 1, TC 2
For gas solenoid valves, quick opening or slow open-
ing with start gas rate.
TC 3
With fitted auxiliary valves for quick or slow opening
gas solenoid valves as well as for motorized valves.

WARNING
Electric shocks can be fatal!
– Before working on possible live components,
ensure the unit is disconnected from the power
supply.
– Incorrect wiring may result in unsafe states and
the destruction of the tightness control, the au-
tomatic burner control unit or the valves.
– Do not reverse L1 (+) and N (–).
– Cable cross-sections must be designed for the
current rating of the selected external fuse.
– The valve outputs on the automatic burner con-
trol unit connected to the TC must be safe-
guarded by an external slow-acting fuse of max.
5 A (e.g. in the automatic burner control unit).
▷Wiring to EN60204-1.
▷
Use connection terminals with a cable cross-
section of max. 2.5mm2.
▷ Conductors which have not been connected
(spare conductors) must be insulated at their
ends.
▷Do not set the remote reset so that it operates
(automatically) in cycles.
▷ The data on the type label must comply with the
mains voltage.
▷ Length of the connection cable, see page 10
(Technical data).
CAUTION
Please observe the following to ensure that the unit

The longer the measurement timet
M
, the greater
the sensitivity of the tightness control. The longer
the measurement time, the smaller the leakage
rate at which a safety shut-down/fault lock-out
is triggered.
▷ For all CG versions, the measurement
timetMmust be set to 5s on TC1C.
▷If no leakage rate is specified, we recommend
the max. measurement time is set.
▷ Within the scope of the European Union, the
maximum leakage rate QLis 0.1% of the maxi-
mum flow rate Qmax. [m3/h (n)].
▷If a leakage rate is specified, find the measure-
ment timetMfrom the following:
Qmax. = max. flow rate [m3/h]
QL= Qmax. [m3/h] x 0.1% = leakage rate [l/h]
pu= inlet pressure [mbar]
VP= test volume [l], see page7 (Values for
valve and pipe volume)
▷ The tightness control TC requires a minimum
start rate in order to carry out tightness tests
on slow opening valves:
up to 5l (1.3gal) test volume VP= 5% of maxi-
mum flow rateQmax., up to 12l (3.12gal) test
volume VP= 10% of maximum flow rateQmax..
 Determine measurement time tM.
▷Measurement times tMfor V1 and V2:
tM[s] =
2.5 x pu[mbar] x VP[l]
QL[l/h]
▷
The entire test period is made up of the meas-
urement timestMof both valves and the fixed
opening timetLof both valves together:
