Annunciation Contacts
Contacts for customer use are provided and wired to TB1 and TB2 as follows for use as annunciators of Bypass unit
operation. All are 5 amp at 120 VAC contacts.
Programmable Output Relays 1, 2 and 3 may be re-programmed via DIP switches S2 and S3 on the Bypass Control
PCB A2. These relays provide form C “dry contacts” for customer use in annunciation to Building Automation Sys-
tems or general duty in other control logic circuits. Each contact is rated for 5 amps at 120 VAC.
The additional programmable output relay functions are described in the table below:
See Table 1.3 for DIP switch positions required to achieve these functions.

Building Automation system Run/Stop circuit:
A control terminal block position (TB1, terminals 2 and 9) is provided to connect the Normally Open (NO) Run/Stop
contact from a BAS or other remote controller for auto mode control.
There must be continuity between these terminals in order for the motor to run, in auto mode.
Safety Interlock Circuit:
A control terminal block position (TB1, terminals 1 and 9) is provided to connect the series circuit of Normally
Closed (NC) safety devices such as: freeze up thermostats, smoke/fire sensors, high pressure limits, temperature lim-
its or vibration detectors.
On power up the E7B_ _ _T or E7B_ _ _Y will display a red “Safety Open” LED in the “System Status” area of the
front control panel if a normally closed “Safety Circuit” has not been installed between TB1-1 and TB1-9 on PCB
A2. This condition will prevent Drive or Bypass operation.
1 of 3 items needs to be done before the motor can be started:
1) Install a NC “Safety Circuit” between TB1-1 and TB1-9 on PCB A2.
2) Install a jumper between TB1-1 and TB1-9 on PCB A2. This method should be used if a “Safety Circuit”
will be added later in the installation.
3) De-activate these terminals by moving DIP switch S2-7 to the ON position (toward the enclosure door). This
solution is only suggested if a “Safety Circuit” will never be applied to the drive system.
Building Automation System Interlock Circuit (Drive and Bypass enable
input):
A control terminal block position (TB1, terminals 3 and 9) is provided to connect Normally Open (NO) enabling con-
tacts such as: damper end switches or occupied cycle timers.
When a Run command is received in HAND or AUTO mode, the E7B_ _ _T or E7B_ _ _Y will display a red
“Damper/BAS” LED in the “System Status” area of the front control panel. This condition will prevent Drive or
Bypass operation.
1 of 3 items needs to be done before the motor can be started:
1) Install a “BAS Interlock Circuit” between TB1-3 and TB1-9 on PCB A2.
2) Install a jumper between TB1-3 and TB1-9 on PCB A2. This method should be used if a “BAS Interlock
Circuit” will be added later in the installation.
3) De-activate these terminals by moving DIP switch S2-8 to the ON position (toward the enclosure door). This
solution is only suggested if a “Safety Circuit” will never be applied to the drive system.

Analog Inputs
The Drive has two analog input terminals for use as auto mode speed command (terminals A1 & A2) and feedback
(terminal A2) input.
Control Circuit Analog Input Terminals on PCB A2
All control inputs are landed on TB1 through TB5 on PCB A2.
TB3-3 is an analog input terminal and may be connected to either Drive terminal A1 or Drive Terminal A2, to maxi-
mize input flexibility, using DIP switches S1-3 and S1-4. The factory default is TB3-3 connected to Drive terminal
A2. With this connection, the input signal level can be either 0 to 10 VDC or 4 to 20 mA. The signal level selection is
controlled by DIP switch S1-2 and Drive parameter H3-08.
TB5-9 is also an analog input terminal, it is always connected to Drive terminal A2.
See Table 1.5, Figure 1.2 and Schematic Diagram E7B-10 for clarification of the analog input configuration and
applications.

Analog Input (Drive Speed Control Circuit) Wiring
Keep this lead length as short as possible (50 m max.) to maintain signal quality. Insulated twisted shielded pair wire
(2 conductor # 18 ga, Belden 8760 or equivalent) is required. Do not run these wires in the same conduits as other AC
power or control wires. The shield must be connected on this end only, stub and isolate the other end. The signal
employed is 4 to 20 mA with parameter H3-08 set for “2: 4 - 20 mA”. For 0 to 10 VDC, parameter H3-08 is set for
“0: 0 - 10 VDC” and the control PCB DIP switch S1-2 must be in the OFF position.
When setting speed commands from an external speed potentiometer (and not from a Digital Operator), use shielded
twisted-pair wires and ground the shield to terminal PE, as shown in Figure 1.3. Terminal numbers and wire sizes are
shown in Table 1.11.

Analog Outputs
Two analog outputs are provided, both can be configured for a signal level of 0 to 10 VDC or 4 to 20 mA. The signal
level is controlled by the position of jumpers J2 and J3 on Control PCB A2 and by the values selected for Drive
parameters H4-07 and H4-08.
Configuring the Analog Outputs:
Programming the Analog Outputs:
The TB3-4 and TB5-6 analog outputs can be programmed to be proportional to any of the following Drive variables.
See the H4-0X parameters in programming manual TM.E7.02 for additional programming details.

Serial Communications:
Terminals are provided for “full duplex” or “half duplex” connections to the Drive for RS422/RS485 serial communi-
cation.
For “half duplex” operation via Metasys N2 protocol (enabled with option J), APOGEE FLN protocol (enabled with
option U) or Modbus protocol (enabled with option V) field configuration of these terminals is required.
When no cost options J, U or V are ordered:
• Jumpers are provided for field installation on terminals TB4-1 to TB4-3 and TB4-2 to TB4-4.
• The E7 Drive is programmed to enable the appropriate protocol (parameter H5-08), baud rate (parameter
H5-02), RTS control (parameter H5-07) and error detection time (parameter H5-09).
Option L (LonWorks) does not require jumpers and (with the exception of H5-07) employs the same parameter set-
tings as Modbus.
For co-ordination with other E7 Technical Manuals, the table below provides the equivalency between E7B_ _ _T or
E7B_ _ _Y Control PCB A2 terminal designations and E7 Drive terminal designations used in TM.E7.01, TM.E7.02,
TM.E7.21, TM.E7.22 and TM.E7B.01.
