Lockout occurs on all occurrences of flame failure.
INSTALLATION
The Programmer Modules are used with the
Fireye modular MicroM Chassis
(P/N MEC320, MEC320RC, MEC320R,
MEC320D and MEC320C for 120VAC and
MEC480 for 230 VAC). They are installed
in the chassis by grabbing hold of the pro-
grammer module by the ridged finger grips
on the side on the module, aligning the mod-
ule with the guide slots on the opening far-
thest from the transformer, and inserting the
module into the pin connectors.
