Discrete Inputs & Emergency Generator Applications
(
T1 T2)
The wiring or use of Discrete Inputs is optional — skip this section if
you don’t plan to use this interface. Discrete Inputs may be wired to the TS-
1001 console with 18 AWG (1.0 mm), type TFFN, or THWN wire. You may also
use THHN wire in sizes larger than 18 AWG (1.0 mm).
Emergency Generator Applications ( T1)
Emergency backup-power Generator run-relay(s) are wired to the Discrete
Input interface terminals at the TS-1001 console. A run-relay closure will stop a
leak test on the associated generator fuel tank. When the generator run-relay
opens (generator stops running), a run report is produced at the console, which
shows the total and hourly fuel consumption rate during the run cycle.
You must use dry run-relay contacts for this interface, since the TS-1001 supplies
+5 VDC digital logic power at the IN — input — terminals.
It is recommended that you use: IN 1 & GND for Generator 1 /fuel
supply Tank #X, and IN 2 & GND for Generator 2 /fuel supply
Tank #Y. The specific fuel tank(s) assigned are “programmable”.
See Figure 7-9a for wiring details.
Non-Standard Power Requirements
The Tank Sentinel console power must be maintained on a power transfer
supply for emergency backup Generator applications. In addition, the TS-1001
Line Power must be supplied through a UPS (Uninterruptible Power Supply).
See Figures 7-3 and 7-9b for Emergency Generator Applications.
Programming & Testing Discrete Inputs ( T1 T2)
Program the tank gauge and test the discrete inputs for proper operation after
installation. See the Tank Sentinel User’s Guide for reports, and programming
issues.
