5.2.5.1 EPROM Storage and Handling
MX through hole control modules contain EPROMs that are fragile and static-sensitive integrated
circuits. Care should be taken in the storage and handling of the EPROMs.
Do not ship or store EPROMs near strong electrostatic, electromagnetic, magnetic or radioactive fields.
Do not remove labels from EPROMs.
Store EPROMs in static-free containers with care to prevent breakage from shock or damage to pins.
Always use an ESD (ElectroStatic Discharge) wristwrap and proper grounding techniques when
removing or installing EPROMs. Flowserve Limitorque provides a kit which contains an ESD wristwrap
with proper grounding instructions; P/N 102424. Please contact Flowserve Limitorque service at
(434) 528-4400 for purchase.
5.2.5.2 EPROM Removal
It is recommended that an IC (Integrated Circuit) insertion/extraction tool be used to remove EPROMs
from the socket. Flowserve Limitorque provides a kit which contains an EPROM removal tool;
P/N 102424.
5.2.5.3 EPROM Installation
It is recommended that an IC insertion/extraction tool be used to hold the EPROM for installation.
Flowserve Limitorque provides a kit which contains an EPROM removal tool; P/N 102424. To insert a
replacement EPROM, use the following procedure:
The notch at one end of the EPROM must be lined up with the notch at one end of the socket. If the
EPROM notch is not matched to the socket notch, the EPROM will be damaged when the unit is
powered. Gently place the pins of one side of the EPROM into the socket holes in the correct side of the
socket.
Roll the EPROM over until the pins on the other side are each lined up with the socket holes. You may
have to use slight pressure to line up the pins. When you are sure all pins are in line with the socket
holes, firmly push down on top of the EPROM until the pins are well seated in the socket.
NOTE: A problem that can frequently occur when inserting ICs into sockets is if one or more pins are
misaligned, missing the intended socket hole. In this case, the affected pins do not make contact. The
problem is difficult to see because the pins can appear to be in the socket hole. After installing the
EPROM or other IC, always examine both rows of pins very carefully to ensure that the pins are aligned
correctly with the IC.
