General Information
Specification Information
The TS-ROM2 BriteBox ™ is either a four channel (TS-ROM2/4) or eight channel (TS-ROM2/8) programmable, dry-relay-
contact, output control device. The states of the channel relays and contacts can be programmed to change in response
to the occurrence of alarms. The electronics are housed in an enclosure which is approximately 7 inches high, 5 inches
wide and 3 inches deep. The four enclosure mounting holes will accept #8 fasteners.
The TS-ROM2 (Relay Output Module) is provided with an 18 inch (max. length) BriteBus ™ serial interface ribbon cable
(P/N 600-0052) which is internally connected to J1. Terminal Strip J10 has sixteen output terminals which are divided
into two output ( OUT n) terminals per channel. Each OUT n channel has one output terminal in series with the channel
relay’s - C (common) contact, and the other output terminal is in series with its 3 Amp output channel fuse and either the
NO (normally open) or NC (normally closed) relay contact. The position of the output channel fuse determines the de-
energized relay’s NO or NC contact selection. In addition, each output channel has a relay on/off status LED. Finally, the
TS-ROM2 is provided with an “active on/active off” switch (SW1: 1-8) that allows a channel relay to be energized in either
an alarm (active switch: off) or no-alarm (active switch: on) condition.
Up to four 1/2 or 3/4 inch knockouts can be used for the TS-ROM2’s conduit wiring. Do NOT use the top and lower side
conduit knockouts because of space limitations. Jack J2 and the knockout closest to J2 is reserved for the addition of
another BriteBox accessory module. In addition, a spare fuse (BUSS PN: PCC3/INCON PN: 430-0033) is provided and
comes in a seperate, clear plastic bag.
One end of the ribbon cable connector mates to J1 at the TS-ROM2 module, and the other end will connect to J1 at the
ATG console after it has been “pulled” through 3/4 inch flexible conduit. The dispenser pump relay coil wiring, and the
dispenser pump switch wiring, will enter through a conduit at one, or both, of the two 1/2 or 3/4 inch knockouts provided
at the bottom of the TS-ROM2 enclosure. Either of the two relay output channel terminals can be wired to the dispenser
pump relay coil, and the other remaining relay output channel terminal is wired to the dispenser pump switch (refer to
Figure 1).
The TS-ROM2 has an operating temperature rating of 32 o to 131 o F (0 o to 55 o C). Each dry-relay-contact output channel is
fused and is rated for 3 Amps at 250 VAC/1 Amp at 30 VDC.
Note: The TS-ROM2 is shipped in a standard configuration: all channel relays are energized (turned on) during normal
no-alarm conditions, all “active on/active off” switches (SW1: 1-8) are OFF and all output channel fuses are
inserted in the FnNO (Fuse channel #n Normally Open) relay contact position.
Theory of Operation (Standard Configuration)
Serial communication data, logic power and ground are supplied through the BriteBus ribbon cable. During normal no-
alarm conditions (when no product or tank point alarms exist) the data will turn on all of the channel’s relays and relay
status LEDs. While the dispenser pump relay circuit is complete, the dispenser pump is permitted to operate. If the Tank
Sentinel loses power, then all of the channel relays will return to, and remain in, their normal de-energized state
until power is recovered.
If the ATG console receives a tank or point alarm fault signal that has been assigned to control the TS-ROM2 outputs,
then the serial data will selectively turn off the affected channel relays and LEDs. The channel relay contact will open,
creating an open dispenser pump relay-coil circuit. In turn, the dispenser pump relay will drop out, its contacts will open
the dispenser pump power source circuit and the dispenser pump will be inhibited from operating. The dispenser pump
will be disabled from further operation until the fault condition has been corrected. Pressing the ACK key will allow for
a permissive-product-dispensing grace period only if a GRACE PERIOD has been programmed. Also see the Alternate
Uses and Configurations section of this manual for further information.
