When wiring the instrument, you must follow industry standard practice for control and
protection against Electro-Static Discharge (ESD). Failure to exercise good ESD practices
may cause damage to the control.
WIRING
1. Remove cover.
2. To gain access to the wiring terminal blocks, remove the upper and lower screws toward the center
of the display board, and then flip the display board up at a 90° angle.
3. Wire to the two terminals blocks as shown in the wiring diagram.
Note: Depending on the application, it may be only necessary to wire to the smaller terminal block on
the upper board. In that case one of the liquid tight fittings may be removed and replaced with the
provided rubber plug.
4. For liquid tight applications, use only 1/2˝ liquid tight conduit.
5. When wiring is complete, reverse steps 2 and 1. Make sure the cover is properly tightened to the
housing.
INSTALLATION
Mount the instrument in a location that will not be subject to excessive temperature, shock or vibration.
Pressure Connections
Use 1/8 male NPT fittings. When tightening fittings, grasp the brass fitting on the Digihelic
®
II Controller
with a 1/2˝ wrench to prevent the fitting on the Digihelic
®
II Controller from turning.

SET POINT ADJUSTMENT
Adjusting the Digihelic
®
II Controller Set Points is quick and simple. Instead of setting a set point and
deadband, simply adjust SP1H or SP2H for the desired relay turn on point, and then adjust SP1L or SP2L
for the desired relay turn off point.

(in. w.c.)
In the above graph, an instrument with a 1.0˝ range would have the SP1 relay turn on at 0.8˝ and off
at 0.4˝. SP1H sets the relay turn on point, and SP1L sets the relay turn off point. The relays outputs
normally function in the direct acting mode, which means the relays turn on with an increase in
pressure. SP1 may be configured to act as a reverse acting relay (refer to the 1SP SUB MENU setting,
page 15). When set for reverse acting, SP1H sets the relay turn OFF point, and SP1L sets the relay turn
ON point. SP2 is always direct acting.

rESO (Resolution) SUB MENU
The Digihelic
®
II Controller is capable of displaying four digits of resolution. However, at very low
pressures the instability of the pressure may cause fluctuations in the least significant digit
causing the least significant digit to be of little value.
Three digit resolution (3DIG ) can only be active when there is at least one digit to the right of a
decimal.
3DIG - Set display for 3 digit resolution
4DIG - Set display for 4 digit resolution
Pd.S (Process Display) SUB MENU
STD - Display reads pressure, velocity, or flow values
PCT - Display reads % of full scale value
When the display is reading percent, PCT is displayed in the upper right of the display. The
percent display is only available in pressure operation.
DAMP (Dampening) SUB MENU
Adjust from 1-16
Dampening stabilizes the display from instabilities due to things such as vibration and
excessive pressure fluctuations. The dampening setting adjusts the amount of readings that
are averaged for each display update. Adjust the dampening value until the display reads a
stable value for the application.
