c. Disconnect the ignitor wire lead connector at the mating connection adjacent to the ig-
nitor.
d. Loosen the screws securing the clamps holding the detector PCB interconnect in place.
The following steps require protection against ESD (Electro- Static Discharge).
`
Use a grounded wrist strap (part no. 9300- 0969 - large, or 9300- 0970 - small)
connected to a suitable ground. Failure to heed this caution may result in
damage to the instrument.
When storing or in between handling of PCBs (Printed Circuit Boards), always
`
place them in static control envelopes or enclosures.
e. Remove the FID detector PCB by sliding it
out of the main PCB (at the right side of the
instrument). Removal of the PCB will with-
draw the interconnect from the thermal
strap. Use caution to avoid damaging the
spring at the end of the interconnect.
f. Remove the three screws securing the col-
lector mount to the thermal strap.
g. Remove the collector mount and collector
assembly as a unit.
The following steps require protection against ESD (Electro- Static Discharge).
`
Use a grounded wrist strap (part no. 9300- 0969 - large, or 9300- 0970 - small)
connected to a suitable ground. Failure to heed this caution may result in
damage to the instrument.
When storing or in between handling of PCBs (Printed Circuit Boards), always
`
place them in static control envelopes.
h. Install the FID detector PCB by sliding it
into its mounting location on the main PCB
(at the right side of the instrument). Instal-
lation of the PCB will insert the interconnect
into the thermal strap. Use caution to avoid
damaging the spring at the end of the inter-
connect.
i. Tighten the screws on the clamps which
secure the interconnect to the thermal
strap.
j. Install the collector mount and collector as-
sembly as a unit.
