Repair Heated Hose
Refer to the heated hose manual 309572 for hos e
replacement parts.
Check Hose Wires
1. Perform Shutdown, page 50.
Note
Whip hose must be connected.
2. Remove cover (CV).
3. Disconnect system wires from the Reactor.
4. Disconnect hose wires (HW) from terminal block
(TB), see Fig 3.
5. Usin
g an ohmmeter, check between the hose
wire
s (HW). There should be continuity.
6. If hose fails test, retest at each length of hose
from the system out to the gun, including whip
hose, until failure is isolated.
7. Reconnect wires and install cover (CV).
Check RTD Cables and FTS
1. Perform Shutdown, page 50.
2. Disconnect RTD cable (C) at Reactor (SC).
3. Test with an ohmmeter between pins of M8 cable
connector C.
Note
Do not touch outer ring with test probe
while measuring resistance.
M8 Connector Pin s Resistance
3 to 1 approximately 1090
ohms
3 to 4 approximately 1090
ohms
1 to 4 0.2 - 0.4 ohms
2toany
infinity (open)
4. Retest at each length of hose, including whip
hose, until failure is located.
5. If the FTS is not reading properly at the end of
the hose, connect FTS directly to RTD cable (C)
at the manifold.
6. If the FTS reads properly at the manifold but
not at the end of the ho se, check cable (C)
connections . Verify they are tight.

Note
To assist in taking readings, order RTD
Test Kit 24N365. Kit includes two cables:
one cable with a compatible female M8
connector and another cable with a male
M8 connector. Both cables have stripped
wire at the other end for easy test probe
access.
