DO NOTinstall in closed and humid environment, or in an area subjected to continualheavy MOUNT: For Wall Mounting, install controller vertically on flat, securesurface.

6 Use the enclosed template to locate mounting screw holes. Followcomplete mounting instructions on : For free-standing installation on a pedestal, follow the instal-lation instructions in the pedestal : The controller should not be placed where it is exposed to atemperature exceeding 130 1. To begin, remove the lower panel by unfastening the screws located onHOOK-UP each side. Follow the wiring diagram shown in Figure 1, Strip wiresapproximately l/4 (do not bend exposed end). Insert straight bare wirebetween plates of sure grip terminal. Tighten screw firmly. Follow allapplicable local electrical wiring codes,Figure 1 COMMONIMPORTANT: Use a separate (dedicated) valve common for each : Make certain that the 120 VAC 60Hz supply is attached to the blackand white wires of the transformer.

7 The yellow and red wires go to the 24 VAC input on the terminals of the : NEVER short wires in order to identify a station or to verify powerfrom 24-volt side of transformer. This will result in damage to controllerand/or A maximum of FOUR 4-watt solenoid valves may be connected to eachstation. Exception: MC-4plus & -6p/us, maximum of TWO 4-watt maximum of FOUR 4-watt solenoid valves may be programmed to In cases where a pump is to be controlled by the master valve output, DONOT drive the pump directly from the controller. The master station must beconnected to the coil of a 24 VAC relay, such as an Essex# 184-20105-101 Z( irri - trol part no.)

8 I 1001). The pump latch relay should be set up by anelectrician so that a switch closure will activate the latch relay coil, turning onthe pump. The switch contacts of the Essex relay should be connected tocontrol the latch relay coil (See Figure 2). The relay should be mounted atleast 5 feet from the controller box and the box MUST be must follow all local electrical wiring / 440 Before power is turned on, re-check all leadsconnected to the terminal block for shorts and/orincorrect terminal assignment. Then turn on power Battery Back-up: The controller is equipped with a rechargeable batteryback-up circuit in case of a temporary power failure (batteries not included).

9 The batteries will retain real time and will hold all program information forabout 4 The battery pack is located on the back of the Board. This packis designed for 4 AA NICAD RECHARGEABLE batteries (notincluded).CAUTION: Use of other types of batteries may damage IT IS MANDATORY that the batteries be installed only AFTER power is turned on and programming has been : Whenever working in the field while power is on, the commonwire must be disconnected from the controller s terminal block. This willeliminate any possible 24-volt controller is a solid-state microcomputer that may be affected bytransient surges and electromagnetic interference.

10 Care must be taken notto install controller on a circuit controlled by a switch or on the same circuitas a high power user ( refrigerator, air conditioner or a large horse-power pump or motor). In addition, the controller must be installed at least 15feet from a high power user. Valve and power wires must also be routedaway from high power users. This controller has been equipped with a floating valve common. It is notreferenced to earth ground. This will not affect operation of your SERIESCONTROLLERSFor safety, transient protection and increased reliability, con-troller MUST be should be installed using a three wire 110 VACsupply with a verified third wire ground.
