Page 2INSTALLATION INSTRUCTIONSIMPORTANT: Completely read and thoroughly understand these instructions before proceeding to install andwire the control. This manual is a generic guide and may not be specific to the panel provided. Refer to the partnumber for specific options chosen on drawing TD-198500 sheet 1.
Mount control box vertically on wall or other solid structure. The maximum distance between the control box andthe location of the electrodes is determined by the sensitivity of the 16M control(s). This information is supplied
on Form 167 (Bulletin P/N 100212-1).
WIRING INSTRUCTIONSNOTE: All wiring shall be in accordance with the National Electrical Code.
The minimum allowable wire size is 14 AWG and of type THHN or MTW.
The ground terminal provided inside the enclosure, on the back panel, must be connected to electrical ground.
Caution: Bonding between conduits must be made.
All conduit entrances and any external metal parts that may become energized must be grounded via the groundterminal provided on the back panel.
Circles with diagonals
on wiring diagram represent terminals provided for external connections.
Connections to these terminals should be made using UL approved crimp type spade lugs. The maximum
allowable connections per terminal are 2.
Terminal pairs 3 – 10 are isolated load contacts and must be wired in series with its load and that series branch
circuit connected across a power source compatible with the load.
Connect terminal pair 1 – 2 to AC supply line of electrical characteristics indicated on data label and drawing.
Fuse protection has not been provided. Do not exceed electrical characteristics indicated on data label anddrawing. Maximum fuse rating is not to exceed 3 AMPS.
Connect terminals pair 3 – 4 into the motor starter circuit of pump #1. This circuit not to exceed 3AMP @ 120
VAC.
Connect terminals pair 5 – 6 into the motor starter circuit of pump #2. This circuit not to exceed 3AMP @ 120
VAC.
Connect terminals pair 7 – 8 into the circuit of the remote HIGH level alarm device. This circuit not to exceed
3AMP @ 120 VAC.
Connect terminals pair 9 – 10 into the circuit of the remote LOW level alarm device. This circuit not to exceed
3AMP @ 120 VAC.
Electrode Wiring
Wiring must be provided to the electrodes as shown on the drawing provided. The electrode wiring should bethermoplastic insulated and be installed in a separate dry metallic conduit. Terminal 20 must be grounded to thevessel if metallic. If the electrode fitting used has a metallic body and is supported directly upon a metallic vessel,
the ground connection is facilitated by securing that end of the ground conductor beneath the head of one of thescrews which fasten the terminal housing to the body of the fitting. When the vessel is non-metallic, terminal 20
must be connected to an additional electrode of length equal to or longer than, the longest electrode.
Float Switch Wiring
Wiring must be provided to the float switches as shown on the drawing provided. The float switches wiring shouldbe thermoplastic insulated and be installed in a separate dry metallic conduit.
Connect terminals 11 and 12 to the normally open HIGH level float switch.

Page 3Connect terminals 13 – 18 to the normally open pump start and stop float switches based on the pumping
operation (i.e. pump down).
Connect terminals 19 and 20 to the normally open LOW level float switch.
OPERATING INSTRUCTIONS
Hand-Off-Automatic selector switches may be provided for the pumps allowing them to be operated automaticallyor manually. To energize the pumps, turn the respective switch to the “Hand” position. To de-energize thepumps, turn the respective switch to the “Off” position. These switches will normally be in the “AUTO” positionand operation will then be as follows.
The panel is equipped with an automatic pump alternator. The pumps will alternate when the lead pump stops
beginning with pump #1. When the level rises to lead pump electrode or float pump #1 will energize. When thelevel recedes to the pump stop(s) electrode or float the alternator will sequence to pump #2. On the next leadpump start pump #2 will energize. Should both pumps be required then both pumps will energize and the cycle
will reset to pump #1.
Pump Down
The lead pump will be started when the tank level rises to the lead pump START electrode or float and willcontinue in operation until the level is reduced below pump(s) STOP electrode or float.
Should the pump be unable to meet the demand or fail completely and the level rises to the lag pump START
electrode or float, the lag pump will be started and will continue in operation until the level is reduced below
pump(s) STOP electrode or float.
Pump UpThe lead pump will be started when the tank level recedes below the lead pump START electrode or float and willcontinue in operation until the level rises to the pump(s) STOP electrode or float.
Should the pump be unable to meet the demand or fail completely and the level recedes below the lag pump
START electrode or float, the lag pump will be started and will continue in operation until the level rises to thepump(s) STOP electrode or float.
High Alarm
If the tank level rises to the HIGH LEVEL electrode or float, the high level alarm light will illuminate.
If the audible alarm option was chosen the following will also occur:
The audible alarm horn will sound and the contacts connected to terminal pair 7 – 8 will close. The contact willremain closed until the high level condition is corrected. The audible alarm can be silenced by momentarily
depressing the SILENCE pushbutton, however, the light will remain on until the abnormal condition is corrected.
Low Alarm
If the tank level rises to the LOW LEVEL electrode or float, the low level alarm light will illuminate.
If the audible alarm option was chosen the following will also occur:
The audible alarm horn will sound and the contacts connected to terminal pair 9 – 10 will close. The contact willremain closed until the high level condition is corrected. The audible alarm can be silenced by momentarily
depressing the SILENCE pushbutton, however, the light will remain on until the abnormal condition is corrected.
