1. INTRODUCTION
The Model 4999 Terminal Box is intended for use with Geokon Vibrating Wire Sensors
with or without Thermistors. Various models are available:
Model 4999-11-2S for up to 2 VW Sensors with Thermistors
Model 4999-11-4S for up to 4 VW Sensors with Thermistors
Model 4999-11-8S for up to 8 VW Sensors with Thermistors
Model 4999-16VTS for up to 16 VW Sensors with Thermistors
Model 4999-32VTS for up to 32VW Sensors with Thermistors
Model 4999-32VWS for up to 32 VW Sensors only. (Without Thermistors)
The Terminal Box makes it easy to manually connect a Readout Box (GK-404 or
GK-405), to a variety of vibrating wire sensors by means of color-coded terminal posts,
mounted below the rotary switches on the face panel of the Terminal Box, to which the
flying leads (patch cord) of the readout box can be clipped. The rotary switch is used to
select which “channel” or sensor is being read by the Readout Box.
The cables from the sensors are passed into the Terminal Box interior through weather
tight entries mounted on the bottom or side of the enclosure. It is important that any
unused cable entries be sealed off by tightening the unused nylon cord grips onto the
white plastic plugs provided for that purpose.
The sensors are protected from over-voltages by means of Gas Discharge Tubes
mounted on the terminal boards. An earth ground lug is provided on the outside of the
enclosure for connection to an earth ground rod.
The Terminal Box is a NEMA 4X style enclosure, environmentally protected
(weatherproof) by means of a hinged cover that has a seamless “foamed-in-place”
gasket that is pressed firmly against the enclosure when the two clamps holding the
cover are closed. The Terminal Box itself is made from fiberglass reinforced polyester.
Polyester mounting brackets with bolt-holes, on top and bottom of the Terminal Box,
allow it to be bolted to any vertical surface.

2. MOUNTING THE TERMINAL BOX
The Terminal Box should be mounted to a flat vertical surface using the holes in the
mounting brackets, or “feet”, at the top and bottom of the enclosure. For the over-
voltage surge protection to be effective the earth ground lug on the outside of the
Terminal Box needs to be connected by a thick copper wire to an earth ground. This
can be a copper rod driven into the ground or, metal objects, such as plumbing pipes, or
electrical conduits, etc, which are themselves well grounded. Copper earth grounding
rods and ground wire straps are available as accessories.
3. CONNECTING THE SENSORS TO THE TERMINAL BLOCKS
The Terminal Box uses spring-loaded type terminal blocks.
Pass the sensor cable through the water tight entry into the inside of the Terminal Box
and connect to the appropriate 5-position, spring-loaded terminal block, following the
instructions of the appropriate wiring diagram. Refer to the wiring diagram fixed to the
inside of the cover, or to the wiring diagram in Section 4 of this manual. When using the
spring type terminals to make the connection, depress the spring lever, poke the bare
wire into the adjacent hole and then release the spring. Check that a good connection
has been made by tugging on the lead wire. After the connections have been made,
tighten the nut on the waterproof connector. This must be done to ensure that
water does not enter the enclosure.

APPENDIX A. MODEL 8032-27 AND LOAD CELL WIRING
Connect the “common” VW- conductor from the load cell to the 8032-27 by lifting up on
the orange tab located on the opposite side of the six black conductors, inserting the
common conductor fully into the 8032-27 (Figure 1), and then pushing down on the
orange tab until it snaps into place. Refer to Table 1 to identify which conductor carries
the common VW- signal.
