Connect safety limit thermostats (manual reset) in the line (e.g. «SB»)
‚
Remote reset
When connecting lockout reset button «EK2» between terminals 21 and
- 3: For remote reset only
- 1: For remote reset and remote emergency shutdown
ƒ
With LAL...: Required switching capacity of
- switching devices connected between terminals 4 and 5 (refer to «Technical data»)
With LAL2... / LAL3... / LAL4...: Required switching capacity of
- switching devices connected between terminal 12 and «LP» (refer to «Technical data»)
- «LP» (refer to «Technical data»)
„
When using series connection, the control contacts of other devices contained in the burner plant must be con-
nected as follows:
To terminal 4 or 5 ® contacts that must be closed from startup to controlled shutdown ® otherwise no startup
or shutdown
To terminal 12 (not with LAL1...) ® contacts that must only be closed on startup ® otherwise no startup
To terminal 14 (not with LAL1...) ® contacts that must be closed no later than at the beginning of «t3» or «t3´»
and that must remain closed until controlled shutdown occurs ® otherwise lockout
…
Maximum current draw, refer to «Technical data»
†
«Z» connected to terminal 15 ® «t3´» and «t3n»
‡
Connection of «BV...» to terminal 20, refer to «Connection examples»
ˆ
When using burners without air damper, or with an air damper not controlled and monitored by the LAL..., ter-
minal 8 must be connected to terminal 6
‰
Wire link «B» clearly marked on the underside of the LAL...
When wire link «B» is fitted, the LAL... initiates lockout if loss of flame occurs during operation. For repetition of
the startup sequence, wire link «B» on the plug-in section of the LAL... must be cut away. Just cutting is not
permitted!
Š
For the permissible lengths and laying of detector cables, refer to «Flame supervision»
