ThePoint Series Mounting and Installation Guidelines (continued) WARNING: ThePoint equipment is rated explosion proof. When installing in explosion hazardous areas [rated “potentially hazardous” (EU) or “hazardous classified” (USA)] observe all national and local regulations as well as specifications in the certificate.
Installation Mounting and Installation Guidelines (continued) • Do not mount a Cote-Shield sensing element through a nozzle that exceeds length of first insulator. • Ensure that there are no obstructions or agitator blades to interfere with sensing element. • Rigid sensing elements can be mounted at any angle. Installation of Flush-Mounted Sensing Elements These instructions apply to all flush on/off sensing elements, models 700-0207-001, 700-0207-002, 700-0207-003, 700-0207-...

Installation Output and LED Status There are two status LEDs located on top of Electronic Unit. The green LED is used to indicate that unit has power. The red LED is used to indicate condition of the relay. See Figure 2-6. Tank Condition Relay Status Power...
ThePoint Series Electronic Unit Remove housing lid to access status LEDs, time delay adjustment, and configuration jumpers. See Figure 2-6. Time Delay Adjustment - 0-60 Seconds Green LED = Power Red LED = Alarm Failsafe Jumper = High Level Down = Low Level...
Installation 2.7.3 Failsafe Failsafe describes the level condition that causes the output relay to de-energize, and also the state of the relay upon loss of power. • High Level Failsafe (hlfs). The relay will de-energize when level is high, indicating high level upon loss of power. (N.O. contacts open and N.C.
ThePoint Series Sensing Element Connection (Integral Sensing Elements) Sensing element connects to the rear side of the circuit board and is factory-installed. The sensing element is sealed to the housing and cannot be removed without permanent damage. Figure 2-7 Sensing Element Connection...

Troubleshooting Section 3: Troubleshooting WARNING If ThePoint instrument is located in a hazardous environment, do not open enclosure cover or make/break any electrical connections without first disconnecting electrical power at the source. Ensure that wiring, electrical fittings and conduit connections conform to electrical codes for the specific location and hazard level.
ThePoint Series Testing Electronic Unit Use the following steps to test the electronic unit: 1. Be sure environment is safe before removing lid from housing. 2. Observe failsafe jumper on circuit board on top of electronic unit (shown in Figure 2-6). Move jumper from current setting to alternate setting [hlfs to llfs or vice versa].
Troubleshooting Testing Relay Circuits Use the following steps to check out the relay circuits: 1. Relay connections consist of a double-pole double-throw (DPDT) relay. 2. The relay contacts are brought out to terminal strips for external switching. See Figure 3-2. 3.
