RJ STYLE CONNECTORS

ED510 Display - See Bulletin ED-5101

Programmer modules (with Engineering code 28 or later) include an RJ45 style connector to connect

to an alpha-numeric display (P/N ED510). The ED510 can snap onto the front cover of the program-

mer module or be mounted remotely (See Bulletin E-8101— Remote mounting kit). The ED580

cable (provided with ED510 Display) then plugs into the RJ45 style connectors on both the ED510

display and programmer module.

Check-Run Switch

The Check-Run switch is located on the top of the EP Programmer Module and can be used to stop

the control in its ﬁring sequence at any time except MTFI. If moved during the MTFI period, it is not

functional and automatic programming continues. It aids in the set-up and adjustment of the burner

linkages, pilot assembly, etc. Refer to Bulletin E-1101 for a complete description of the Check-Run

Switch.

E500 Communication Interface and InTouch Wireless Monitoring System

Programmer modules include two (2) RJ12 style connectors to connect to the RS485 Interface on the

E500 Communication Interface or InTouch Wireless Monitoring System in a multi-drop wiring con-

ﬁguration with other devices or connect to a Modbus network. Refer to Bulletin E-5001 and

INT-1000 respectively. Up to six (6) each of EP programmers and E340 Boiler Controls (12 total)

can be wired in an E500 multi-drop conﬁguration or up to ten (10) to the InTouch. (Unit address 00

to 31). When connected in this manner, a unit address must be set on each programmer module con-

nected to the RS485 interface. (See Unit Address). Programmers can also be connected to the E500

via the standard ﬂat ribbon cables (ED550).

UNIT ADDRESS

There are two methods to program the unit address when the programmer module is connected to the

E500 via the RS485 interface:

Method One (ED510 display only)

1. Press the SCRL key until the screen displays PROGRAM SETUP

2. Press the MODE key and the screen displays PROGRAMMER EP160 (or appropriate model).

3. Press the SCRL key until the screen displays UNIT ADDRESS #00 (or appropriate address).

4. Every time the RESET key is held down for 1 second and then released will increase the address

by one.

5. Maximum address is 31. Then the address will roll over to 00.

Method Two (ED510 or ED500)

1. Make sure the control is not in a lockout condition. If so, press the reset button.

2. Open the operating control (term L1-13).
