6.15.13 Flow Transducer Fault
A. Alarm per 4.5.2 indicates this fault.
B. Scroll of GPM shows flow as: ???
C. Confirm with analog input test of CHNL 2 per 6.10.3.
Corrective Action:
1. Disable transducer by entering user menu per
4.3 and changing GPM xmitter span (item 23)
to "0". Alarm message will turn off. GPM stag-
ing is inactive.
2. Replace flow transducer.
6.15.14 RTD1 or RTD2 Fault
A. Alarm per 4.5.2 indicates this fault.
B. Confirm with analog input test of RTD channels
(steps 5 or 6) per 6.10.3.
Corrective Action:
1. Disable RTD1 and RTD2 by removing respec-
tive connections at J3 13 & 14, and 16 & 17
and replacing each with a 100 OHM resistor.
Both RTD's must have this substitute resistor
even though only one is defective.
2. Ignore 32˚F temperature display.
3. High temperature cut out and no flow shut
down are both inoperative.
4. Replace defective RTD. Observe and perform
any calibration procedure that may accompany
the RTD.
WARNING: Prevent electrical shocks. Disconnect
the power supply before beginning installation.
Failure to follow these instructions could result in
serious personal injury, death, and/or property damage.

INSTRUMENTS AND THEIR USE
With the diagnostics described herein extensive
instruments are not required. However, the instru-
ments used should be quality units to meet the fol-
lowing at a minimum.
Under no circumstances shall any instrument be
used to test any on board components. Especially
risky is an ohmmeter with battery voltage higher than
TTL logic or applied with incorrect polarity.
6.16.1
AC/DC Voltmeter –
– Input impedance shall not be less than
10 MEGOHM.
– Accuracy - AC ± 2% of F.S.
- DC ± 3% of F.S.
– Rated circuit to ground voltage = 1000V.
Note F.S. = Full Scale.
6.16.2
OHMMETER
– Accuracy ± 2
/
1
– Max open circuit voltage =
6.16.3
Millimeter
– Accuracy ± 2% of F.S.
6.16.4
Signal Generator (analyzer) - recommended
A. Beta calibrator Model 434 20mA signal analyzer.
B. Altec calibrator Model 334 4-20mA loop analyzer.
Either instrument may be purchased from your
Local Process Control Distributor.
NOTE: If some other instrument is used it must
float above ground, preferably battery powered.

FIELD REPAIR
6.17.1
General – field repair, except replacing fuses, replac-
ing analog input resistors, and assuring connections,
such as ribbon cable, are correct and secure, is not
recommended.
6.17.2
EPROM Changing – normally EPROMS are not
changed in the field. In an emergency this is the
procedure to be performed when authorized by the
factory.
A. Record all data from the OIP.
B. Turn off all power to the panel.
C. Ground your body. Touch earth ground to dis-
charge static electricity.
WARNING: Electrical shock hazard. Multiple power
sources. The off position of the HAND-OFF-AUTO
switch does not disconnect all of the power sources in
the Technologic panel. All power sources must be dis-
connected prior to entering the control panel. Failure to
follow these instructions could result in serious per-
sonal injury, death, and/or property damage.
D. With one hand only gently pry EPROM (chip U1)
up from its socket alternating from each end in
small increments. Use a small screwdriver. Do not
place free hand on OIP components. Ground free
hand if possible.
E. Insert new EPROM with all pins in the socket and
the notch oriented as chip U2 notch (adjacent
chip).
F. If done carefully, the EPROM will not be corrupted.
G. Turn on power. Enter user menu per 5.1.3 and
check special data for the job at hand.
6.18
SERIAL NO. AND FIRMWARE VERSION NO.
6.18.1
Both of these numbers may be found as the 4th mes-
sage after booting. If the factory is called for informa-
tion or service on this unit the serial No. and firmware
version No. may be requested. They are important to
B&G in order to track the unit.
6.19
MAINTENANCE (Physical)
6.19.1
Electrical – no maintenance is required for the electri-
cal panel except to keep the boards free of dirt and
dust that might hold moisture. Cabinet door should
be kept closed, and the components kept dry.
6.19.2
Mechanical – A Series 1531 pump was lubricated at
the factory. Future lubrication should be according to
the motor manufacturer's instructions.
A Series 1510 pump requires regreasing after every
2500 hours of operation or every six months which-
ever occurs first. Lubricate motor per motor manu-
facturer's instructions.
If there is a danger of freezing, drain the pump.
Inspect pump and system piping regularly.
For leaky seals or gaskets and loose or damaged
components, replace or repair as required.
For more information on the B&G pumps see the fol-
lowing manuals:
1510 (IOM Part #P81673)
1531 (IOM Part #P81567)
