Checking the usage
TC410 for tightness test before every controlled start-
up or after every controlled shut-down in systems
with 2safety valves. Tightness control TC410 can
be used for individual valves, quick opening or slow
opening with start gas rate. The valves are controlled
directly for testing by the TC410. A pressure switch
for gas must be mounted on the interspace between
the valves to be monitored for the tightness test.
This function is only guaranteed when used within the
specified limits– see page5 (Technical data). Any
other use is considered as non-compliant.

Installation
CAUTION
Please observe the following to ensure that the TC
is not damaged during installation:
– Avoid condensation.
– Gas type and inlet pressure pu: dependent on
external pressure switch.
▷Any installation position.
▷
The device must not be in contact with masonry.
Minimum clearance 20mm (0.78").
▷
In the case of very large test volumes VP, an
installed relief line should be of nominal size40
to allow for the discharge of the test volume VP.

Example:
inlet pressure pu= 100mbar,
set switching pressure pu/2 = 50mbar,
max. switching differential 50mbarx 10%=
5mbar.
The switch-on and switch-off pressure must be
between 45mbar and 55mbar.
Wiring
CAUTION
Electric shocks can be fatal!
– Before working on possible live components,
ensure the unit is disconnected from the power
supply.
Please observe the following to ensure that the TC
is not damaged during installation:
– 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(–).
Disconnect the system from the electrical power
supply.
Shut off the gas supply.
Open the housing cover of the TC.
▷Electrical connection: 2.5mm2terminals.
▷
The data on the type label must comply with the
mains voltage.
4 Prepare knock-out holes at the appropriate cable
glands.
▷Use the NO contacts 3COM and 2NO on the
pressure switch (pe/2=pu/2).

Setting the test instant
▷
The test instant (MODE) can be set inside the
housing using a jumper.
▷Mode 1: test before burner start-up with incom-
ing ϑsignal (factory setting).
▷
Mode 2: test after burner run with outgoing ϑsig-
nal and also after switching on the mains voltage.
▷Without jumper = test before burner start-up.
Disconnect the unit from the electrical power
supply.
Unscrew the housing cover.
Set the test instant with a jumper, MODE 1 or2.

Setting the test periodtP
▷
The test period t
P
is set at the works to 10s
(100s) on TC410-1 (TC410-10) and can be
changed with a jumper in increments of 10s
(100s) to a max. of 60s (600s).
▷Without jumper = 60s (600s).
▷
The longer the test periodtP, the smaller the leak-
age rate at which a safety shut-down is triggered.
▷If no leakage rate is specified, we recommend
the max. test period is set.
▷
If a leakage rate is specified, find the test pe
-
riodtPfrom 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 page3 (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 5l (1.3gal) test volume VP= 5% of maxi-
mum flow rateQmax.,
up to 12l (3.12gal) test volume VP= 10% of
maximum flow rateQmax..

–
Before working on possible live components, en-
sure the unit is disconnected from the power supply.
– Fault-clearance must only be undertaken by
authorized trained personnel.
– (Remote) resets may only be conducted by

▷
Press the reset button, see page 4 (Com-

▷
If the tightness control will not start even though
all faults have been remedied, remove the unit
and send it to the manufacturer for inspection.
? Fault
! Cause
• Remedy
? No LED is lit although mains voltage and
ϑsignal are applied?
! Fuse defective.
• Replace 5A slow-acting fine-wire fuse– after
replacing the fuse, start the tightness test several
times and check the program sequence and the
outputs of the tightness control.
• If it does not operate correctly, return the unit to
the manufacturer.
! Mode : test before burner start-up is set; L1
and N are reversed on terminals 1 and2.
• Connect L1 to terminal 1 and N to terminal 2.
! For 24 V DC: polarity of mains voltage on termi-
nals 1 and2 reversed.
• Connect + to terminal1 and– to terminal2.
! Mains voltage too low.
• Compare to details on the type label. Tolerance:
-15/+10% for 110/120VAC and 220/240VAC,
±20% for 24VDC.
? TC repeatedly signals a fault?
! A valve is leaking.
• Replace the valve.
! Pressure switch incorrectly set.
• Set the pressure switch to half the inlet pressure.
! Wiring to the valves reversed.
• Start the program and observe the interspace
pressurepz. The pressure must change during
the TEST phase. Check the wiring.
! Inlet pressure pu< 10 mbar.
• Provide the min. inlet pressure of 10mbar.
! Interspace pressure pzcannot be reduced.
• The volume downstream of the valve on the
burner side must be 5times higher than the
volume between the valves and atmospheric
pressure must prevail.
! The test period tPis too long.
• Adjust tP, see page 3 (Setting the test pe-
riodtP).
? The downstream automatic burner control
unit does not start?
! On the tightness control, L1(+) and N(–) on
terminals 1 and2 are reversed.
• Connect L1(+) to terminal1 and N(–) to termi-
nal2.
? TEST phase running (yellow LED indicator is
lit) although no ϑsignal has been applied?
! Mode 2 set.
• Set jumper to Mode 1, see page3 (Setting
the test instant).

Tightness controls TC require little servicing. We rec-
ommend a function check once a year.
