d. Alarm Adjustments.
(1) General. Following the calibration of the meters of the receiver modules and receiver panels during
installation or corrective maintenance procedures and whenever a repair is made to an alarm circuit in a
receiver module or receiver panel control module, the TLI system is adjusted to establish the levels of
operation of high- and low-level alarms. The procedure for the adjustment of high- and low-level alarm
operation is determined by whether the receiver being adjusted is a receiver module or a receiver panel.
Procedures for each adjustment type follow. In both procedural types, it is assumed that the indication level at
which alarms are to be operated have been determined and marked or recorded during the calibration of the
meter.
(2) Receiver Panel Adjustment. To perform the installation (alarm) adjustments for receiver modules,
proceed as follows:
(a) Place the ON-OFF switch on the front panel in the OFF position.
(b) Disconnect the red, black, and white cable leads connecting to terminals 1, 2, and 3 on the
terminal board associated with the receiving circuits being adjusted.
(c) Disconnect the float simulator cable from terminals 1, 2, and 3 on the float simulator terminal
board.
(d) Connect the red lead of the float simulator cable to terminal 1 of the terminal board associated
with the receiver circuits being adjusted.
(e) Connect the black lead of the float simulator cable to terminal 2 of the terminal board associated
with the receiver circuits being adjusted.
(f) connect the green lead of the floating simulator cable to terminal 3 of the terminal board
associated with the receiver circuits being adjusted.
NOTE
Perform steps (g) and (h) for those tanks, the receiver circuits
for which include low level alarm capabilities.
